This application claims priority to and the benefit of U.S. patent application Ser. No. 16/535,851, filed on Aug. 8, 2019, and entitled “Systems and Methods for Enabling Point of Care Magnetic Stimulation Therapy,” the disclosure of which is expressly incorporated herein by reference in its entirety.
The present invention relates generally to magnetic stimulation and more particularly to systems and methods for enabling point-of-care transcranial magnetic stimulation therapy.
Various medical conditions may be treated by the application of magnetic stimulation to anatomical targets associated with specific pathologies. For example, magnetic or inductive stimulation may be used to produce a changing magnetic field that can be directed to induce an electric current in a target anatomy of a patient. Neurons, muscles, and tissue cells are forms of biological circuitry capable of carrying electrical signals and responding to electrical stimuli. When a changing magnetic field is applied to a target anatomy, an electric field is induced, causing electric current to flow in conductive portions of the anatomy. The flow of electric current stimulates biological tissue, resulting in depolarization of neurons in the tissue, which causes the neurons to be more active or less active depending on factors including pulse frequency and excitability of the target tissue. Additionally, the flow of electric current causes muscles associated with the stimulated neurons to contract. Ultimately, the induced electric current may be used to simulate desired chemical reactions in the target anatomy.
In contrast to other medical procedures for stimulating a target anatomy, magnetic stimulation may be administered in a non-invasive manner. For example, in performing transcutaneous magnetic stimulation, a magnetic field may be passed through the skin of a patient to induce an electric current in the patient's body for stimulating the target anatomy. Such magnetic stimulation may have beneficial and therapeutic biological effects in treating various portions of the body, including muscles, the spine, and the brain. Transcranial magnetic stimulation (TMS) is a non-invasive form of brain stimulation, which uses a changing magnetic field to produce an electric current in neurological tissue at a target region of the brain via electromagnetic induction. TMS therapy utilizes a stimulator connected to a magnetic coil. The magnetic coil is positioned about the patient's head at a position corresponding to the target region of the brain, and the stimulator delivers electric pulses to the magnetic coil, which induces a changing magnetic field. The magnetic field causes an electric current to be induced in the target region of the brain, resulting in stimulation of the corresponding neurological tissue. In some instances, brain stimulation may be achieved by repetitive transcranial magnetic stimulation (rTMS), which uses repetitive electromagnetic pulses applied at repetition rates that enable intended modulation effects of the cortical targets. Various neurologic or psychiatric disorders may be treated using rTMS, including, for example, major depressive disorder (MDD), bipolar disorder, anxiety, obsessive-compulsive disorder, pain (including fibromyalgia), posttraumatic stress disorder, autism spectrum disorder, and addiction. rTMS typically may be used to treat such disorders when standard treatments, such as medications, are not effective or are not well tolerated by the patient due to undesirable side effects.
TMS is currently administered to a patient by a trained clinician at a clinical facility, such as a hospital, a physician's office, or a clinic. Existing systems for performing TMS therapy generally require a patient to be evaluated and treated using the same TMS system, with close oversight of a properly trained clinician to ensure safe and compliant treatment. A course of therapy for a typical patient being treated for MDD or similar neurologic or psychiatric disorder generally requires repetitive daily treatments over a period of three to six weeks. For patients with such illnesses, frequent travel to a facility offering TMS treatment is often a hardship.
Currently, no practical TMS system exists for home or point-of-care (POC) treatment for indications, such as MDD, that require rTMS. Although portable TMS systems have been proposed, such systems do not meet all the requirements for a practical POC TMS system that can safely deliver patient-administered rTMS. Single pulse TMS devices for POC treatment of migraine have been developed and approved by certain regulatory agencies. However, use of single pulse TMS devices is not extendable to treatment of MDD and similar disorders because the treatment protocols for such disorders require repetitive application of much higher power magnetic field pulses, which in turn necessitates greater attention to management of safety risks and higher system power requirements. Other TMS devices have been developed for POC treatment of certain neurological disorders, which use rotating magnets to produce low level magnetic field pulses. Such sub-threshold devices, however, have not been demonstrated to be as effective for treatment of MDD and similar disorders as rTMS administered above stimulation threshold. In sum, current technology does not enable patient-administered POC TMS treatment for indications that require rTMS because existing TMS systems lack the required portability or functionality and/or fail to address the necessary safety and regulatory requirements.
A need therefore exists for improved systems and methods for enabling point-of-care magnetic stimulation therapy to alleviate the burden on patients with neurologic or psychiatric disorders that require repetitive transcranial magnetic stimulation.

The support mechanism 163 is configured to secure the headpiece 161 relative to the head of the subject S, for example, to maintain the headpiece 161 in the pre-determined position. The secure locking means 164 is configured to mount the magnetic coil(s) 146 at a fixed location relative to the body 162. The fixed location of the magnetic coil(s) 146 relative to the body 162 corresponds to the pre-determined position of the headpiece 161 relative to the target anatomy of the subject S. In this manner, when the headpiece 161 is positioned at the pre-determined position, the magnetic coil(s) 146 is properly positioned to direct the magnetic field induced thereby to the target anatomy. In some embodiments, as shown, the secure locking means 164 may include a bracket and one or more fasteners, although other types of means for securely locking the magnetic coil(s) 146 at a fixed location may be used, such as one or more adhesives, glues, mechanical couplings, straps, clamps, and the like. The secure locking means 164 is configured such that the fixed location of the magnetic coil(s) 146 cannot be altered by unauthorized persons, including the subject S. The magnetic coil(s) 146 is mounted at the fixed location by authorized persons during initial setup of the headpiece 161 for the subject S, and the secure locking means 164 prevents movement of the magnetic coil(s) 146 relative to the body 162 after setup. For example, the secure locking means 164 may require a unique key or removal tool for unlocking and allowing movement of the magnetic coil(s) 146.
The headpiece identifier(s) 165 includes one or more identifiers associated with the headpiece 161 and configured to allow the headpiece 161 to be uniquely identified. For example, the headpiece identifier(s) 165 may include one or more of a barcode, a radio frequency identification (RFID) tag, a structural pattern, or other type of unique identifier. The headpiece identifier(s) 165 may include one or more encrypted identifiers. As described below, the headpiece identifier(s) 165 may be included in images captured by the image recording device(s) 147. In this manner, images including the headpiece identifier(s) 165 may be used to determine whether the headpiece 161 is associated with a person wearing the headpiece 161 (i.e., whether the person wearing the headpiece 161 is the intended subject S). Further, images including the headpiece identifier(s) 165 and the head of the subject S may be used to determine whether the headpiece 161 is properly positioned for treatment (i.e., whether the headpiece 161 is positioned at the pre-determined position relative to the head of the subject S). In some embodiments, one or more of the indicators 149 of the treatment system 140 are provided as a part of the headpiece 161. In the example of
As shown in
In the example of
During use of the treatment system 140, the subject S may control operation of the treatment system 140 via a user interface 171. In some embodiments, as shown, the user interface 171 may be provided as a part of the electronics unit 160, although other configurations may be used. The user interface 171 may include a plurality of selectable elements, such as buttons, switches, and the like, for selection by the subject S. For example, the user interface 171 may include a power button, a start button, a stop button, a pause button, and the like to control magnetic stimulation provided by the treatment system 140 during a treatment session. The subject S also may control operation of the treatment system 140 via the audio recording device(s) 148. For example, the audio recording device(s) 148 may capture an audio recording of the subject S including a verbal command (e.g., start, stop, pause, etc.). In some embodiments, the treatment system 140 may respond only to verbal commands by the intended subject S and not verbal commands by other persons. For example, the treatment system 140 may use a first, reference audio recording for the subject S to determine whether a second audio recording captured by the audio recording device(s) 148 is associated with the subject S. Although the treatment system 140 is configured to allow the subject S to control operation of the treatment system 140 during a treatment session, the treatment system 140 alternatively may be operated by an assistant who, like the subject S, has only minimal clinical training.
As discussed above, the treatment system 140 may be configured for a particular subject to enable POC magnetic stimulation therapy according to the subject's magnetic stimulation prescription. After the subject's course of treatment is completed, the treatment system 140 may be reconfigured for subsequent use by another subject according to that subject's prescription. In light of current awareness of infectious and communicable diseases, the treatment system 140 may include certain features and functionality to ensure proper disinfection of the treatment system 140 between use by different subjects. In some embodiments, the electronics unit 160, the headpiece 161, and any accessories and packaging of the treatment system 140 may be compatible with a number of disinfecting methods, including ethylene oxide, alcohol mist or wipe, soap cleansing and rinse, and plasma or ozone techniques. In this manner, the treatment system 140 may be disinfected according to one or more of these methods at the equipment dispensing location by a trained professional prior to a subject obtaining the treatment system 140 for POC therapy. In some embodiments, the disinfecting methods used may be effective in virtually eliminating the subject's exposure to malevolent viruses (e.g., SARS CoV-2) and bacteria (e.g., MRSA) that could be transferred unintentionally with the treatment system 140. In some embodiments, the treatment system 140 may include one or more disinfection indicators 186, 187 configured to indicate that one or more components of the treatment system 140 have been disinfected. For example, the electronics unit 160 may include a first disinfection indicator 186 mounted to the housing thereof, and the headpiece 161 may include a second disinfection indicator 187 mounted to the body 162 thereof. In some embodiments, the disinfection indicators 186, 187 may be visible indicators. For example, a dated chemical strip that changes color when exposed to a disinfectant may be used as a disinfection indicator 186, 187. In other embodiments, an ultraviolet stamp with a disinfection date visible using the image recording device 147 or when illuminated with UV light may be used as a disinfection indicator 186, 187. In some embodiments, when the treatment system 140 is initially issued to a subject, the electronics unit 160, the headpiece 161, and any accessories of the treatment system 140 may be provided in packaging (e.g., one or more sealed plastic bags) having tamper-evident features, such as tamper-evident seals. In this manner, a state of the tamper-evident features may indicate that the components of the treatment system 140 have not been contaminated after disinfection. In some embodiments, an electronic record of completion of disinfection of the treatment system 140 may be created and stored within the magnetic stimulation system 100. For example, disinfection data indicative of completion of one or more disinfection methods and a date of disinfection of the treatment system 140 may be created and stored at the data server(s) 104 and/or the treatment system 140.
In some embodiments, the treatment system 140 may include one or more disinfection verification module(s) 190 for determining that the treatment system 140 has been disinfected prior to initial use by a subject. The disinfection verification module(s) 190 may include computer-executable instructions, code, or the like that, responsive to execution by one or more of the processor(s) 141 perform functions including, but not limited to, receiving first disinfection data for the treatment system 140 or a component thereof (i.e. the electronics unit 160, the headpiece 161, or an accessory), receiving second disinfection data for the treatment system 140 or a component thereof, determining whether the treatment system 140 or a component thereof has been disinfected, or currently is in a disinfected state, based at least in part on the first disinfection data and/or the second disinfection data, and the like. In some embodiments, the first disinfection data may include an indication that the treatment system 140 or component was or was not disinfected at the equipment dispensing location. The first disinfection data may be received from the data server(s) 104, the data storage 150 of the treatment system 140, or another device or system of the magnetic stimulation system 100. In some embodiments, the second disinfection data may include an indication that the treatment system 140 or component currently is or is not in a disinfected state. The second disinfection data may be received from the image recording device 147 of the treatment system 140, one or more detection means 188 for detecting a disinfection status or disinfection state, such as one or more sensors of the treatment system 140, or another device or system of the magnetic stimulation system 100. In some embodiments, the second disinfection data may include one or more images of one or more disinfection indicators (e.g., visible indicator, UV stamp, tamper-evident seal, etc.) of the treatment system 140, which may be acquired using the image recording device 147 or another device. In some embodiments, the second disinfection data may be indicative of one or more disinfection parameters related to a disinfection state of the electronics unit 160, the headpiece 161, or an accessory or packaging of the treatment system 140, which may be acquired using the detection means 188 of the treatment system 140 or another device configured for detecting the relevant disinfection parameter. For example, the detection means 188 of the treatment system 140 may include a sensor for detecting a change in oxygen level within sealed packaging containing a component of the treatment system 140 (e.g., the component may be sealed in a nitrogen environment when disinfected and exposed to ambient oxygen when the seal of the packaging is broken). Additionally, or alternatively, the detection means 188 of the treatment system 140 may include a sensor for detecting a presence of microbes on a component of the treatment system 140 or within sealed packaging containing the component. As another example, the detection means 188 of the treatment system 140 may include a sensor for detecting a presence (or loss or absence) of disinfectant on a component of the treatment system 140 or within sealed packaging containing the component. In some embodiments, the treatment system 140 may enable operation of the stimulator 145 and/or the magnetic coil 146 based at least in part on a determination that the treatment system 140 or a component thereof has been disinfected, or currently is in a disinfected state. In other words, the treatment system 140 may perform a disinfection check prior to enabling use of the treatment system 140 for magnetic stimulation therapy.
The treatment system 140 also may include certain features and functionality to ensure that components of the treatment system 140 and/or data or software utilized by the treatment system 140 have not been tampered with, damaged, or otherwise compromised. For example, in some embodiments, the treatment system 140 may include one or more coil positioning verification module(s) 191 for determining that the magnetic coil 146 is in the predetermined position relative to the body 162 of the headpiece 161. The coil positioning verification module(s) 191 may include computer-executable instructions, code, or the like that, responsive to execution by one or more of the processor(s) 141 perform functions including, but not limited to, receiving coil positioning data for the treatment system 140, determining whether the magnetic coil 146 currently is in the predetermined position relative to the body 162 based at least in part on the coil positioning data, and the like. In some embodiments, the coil positioning data may include an indication that the magnetic coil 146 currently is or is not in the predetermined position relative to the body 162. The coil positioning data may be received from the image recording device 147 of the treatment system 140, one or more detection means 188 for detecting a position of the magnetic coil 146 relative to the body 162, such as one or more sensors of the treatment system 140, or another device or system of the magnetic stimulation system 100. In some embodiments, the coil positioning data may include one or more images of the magnetic coil 146 and the body 162 of the headpiece 161. Such images may be compared to one or more reference images in which the magnetic coil 146 is known to be in the predetermined position relative to the body 162, or such images may be otherwise analyzed to verify positioning of the magnetic coil 146. In some embodiments, the secure locking means 164 may include a tamper-evident feature, such as a tamper-evident seal, and the images may include the tamper-evident feature. In this manner, the images may be analyzed to determine whether or not the tamper-evident feature has been altered (e.g., whether a tamper-evident seal has been broken). In some embodiments, the coil positioning data may be indicative of one or more positioning parameters related to a position of the magnetic coil 146 relative to the body 162, which may be acquired using the detection means 188 of the treatment system 140 or another device configured for detecting the relevant positioning parameter. For example, the detection means 188 of the treatment system 140 may include a sensor for detecting a change in position of the magnetic coil 146 relative to the body 162. Additionally, or alternatively, the detection means 188 of the treatment system 140 may include a sensor for detecting whether or not a tamper-evident feature has been broken or otherwise altered. In some embodiments, the treatment system 140 may enable operation of the stimulator 145 and/or the magnetic coil 146 based at least in part on a determination that the magnetic coil 146 is in the predetermined position relative to the body 162 of the headpiece 161. In other words, the treatment system 140 may perform a coil positioning check prior to enabling use of the treatment system 140 for magnetic stimulation therapy.
In some embodiments, the treatment system 140 may include one or more data verification module(s) 192 for determining that data used by the treatment system 140 has not been tampered with or otherwise altered. The data verification module may include computer-executable instructions, code, or the like that, responsive to execution by one or more of the processor(s) 141 perform functions including, but not limited to, receiving first data for the treatment system 140 or the subject, receiving second data for the treatment system 140 or the subject, determining whether the second data has been tampered with or otherwise altered based at least in part on the first data and the second data, and the like. In some embodiments, the first data may be reference data that is known to be correct for the treatment system 140 or the subject to be treated therewith, and the second data may be data currently stored at the treatment system 140. In some embodiments, the first data may be received from the data server 104 or from the data storage 150 of the treatment system 140, and the second data may be received from the data storage 150. For example, the first data may be stored remote from the treatment system 140 (prior to the treatment system 140 receiving the first data from the remote location), and the second data may be stored locally at the treatment system 140. The second data may be compared to the first data to determine whether the second data has or has not been tampered with or otherwise altered. In some embodiments, the first data and the second data may include one or more of subject data for the subject to be treated, stimulation parameter data for the subject, stimulation history data for the subject, security data for the subject, or other types of data associated with the subject or the treatment system 140. In some embodiments, the treatment system 140 may enable operation of the stimulator 145 and/or the magnetic coil 146 based at least in part on a determination that the second data has not been tampered with or otherwise altered. In other words, the treatment system 140 may perform a data tampering check prior to enabling use of the treatment system 140 for magnetic stimulation therapy.
In some embodiments, the treatment system 140 may include one or more functionality verification module(s) 193 for determining that the treatment system 140 or one or more components thereof are able to function within a predetermined specification (i.e., the components and/or the overall treatment system 140 have not been damaged or otherwise altered in a manner that inhibits or compromises function within the predetermined specification for magnetic stimulation or adversely affects safety or efficacy of the treatment system 140). The functionality verification module(s) 193 may include computer-executable instructions, code, or the like that, responsive to execution by one or more of the processor(s) 141 perform functions including, but not limited to, receiving functionality data for the treatment system 140 or one or more components thereof, determining whether the treatment system 140 or one or more components thereof are able to function within the predetermined specification based at least in part on the functionality data. In some embodiments, the functionality data may be indicative of one or more functionality parameters related to a function of the treatment system 140 or one or more components thereof, which may be acquired using one or more detection means 188 for detecting functionality parameters, such as one or more sensors of the treatment system 140 or another device configured for detecting the relevant functionality parameter. For example, the detection means 188 of the treatment system 140 may include one or more fault detection features or tolerance detection features, which may include one or more sensors, for detecting the relevant functionality parameter. Such features may be configured to detect whether the stimulator 145 is able to properly generate electric pulses, whether the magnetic coil 146 is able to properly deliver magnetic stimulation, and the like. In some embodiments, the treatment system 140 may enable operation of the stimulator 145 and/or the magnetic coil 146 based at least in part on a determination that the treatment system 140 or one or more components thereof are able to function within the predetermined specification. In other words, the treatment system 140 may perform a functionality check prior to enabling use of the treatment system 140 for magnetic stimulation therapy.
In some embodiments, the treatment system 140 may include one or more software verification module(s) 194 for determining that the software used by the treatment system 140 has not been hacked or otherwise altered in an unauthorized manner. The software verification module(s) 194 may include computer-executable instructions, code, or the like that, responsive to execution by one or more of the processor(s) 141 perform functions including, but not limited to, receiving software data for the treatment system 140, determining whether the software used by the treatment system 140 has been hacked or otherwise altered based at least in part on the software data, and the like. In some embodiments, the software data may be indicative of changes to, or attempts to change, the software used by the treatment system 140, and such changes or attempts to change may be analyzed to determine whether they were authorized or unauthorized. In this manner, unauthorized changes or attempts to change the software used by the treatment system 140 may indicate that the software has been hacked. In some embodiments, the software verification module(s) 194 may perform functions such as code comparison, checksum comparison, image mapping, intrusion detection and flagging, encrypted revision control, and the like to determine whether or not the software used by the treatment system 140 has been hacked or otherwise altered in an unauthorized manner. In some embodiments, the treatment system 140 may enable operation of the stimulator 145 and/or the magnetic coil 146 based at least in part on a determination that the software used by the treatment system 140 has not been hacked or otherwise altered in an unauthorized manner. In other words, the treatment system 140 may perform a software check prior to enabling use of the treatment system 140 for magnetic stimulation therapy.
To enable point-of-care magnetic stimulation therapy, the magnetic stimulation system 100 may execute one or more process flows. An example process flow 180 for managing and performing magnetic stimulation to treat a patient is depicted in
At block 181 of the process flow 180, the prescribing system 110 may determine stimulation parameter data for a subject. The stimulation parameter data may be determined based at least in part on one or more indications of user input provided by a trained clinician operating the prescribing system 110. The stimulation parameter data may include a plurality of parameters associated with operation of the stimulator 115 or the magnetic coil 116 for the subject. For example, the parameters may include a magnitude and a timing sequence of electric pulses generated by the stimulator 115, a magnitude of magnetic stimulation delivered by the magnetic coil 116, a position of the magnetic coil 116 relative to a target anatomy of the subject, and other parameters defining a treatment protocol for treating the subject's disorder (i.e., the subject's magnetic stimulation prescription). Use of the prescribing system 110 may begin with determining the subject's motor threshold level and motor threshold location in a conventional manner. The clinician may interact with the user interface 132 to cause the stimulator 115 to generate magnetic pulses and to cause the magnetic coil 116 to deliver magnetic stimulation to the subject's brain. The clinician may move the magnetic coil 116 over the subject's head to isolate a particular muscle location in the subject's brain and may vary the power level of magnetic stimulation to determine the subject's motor threshold level and motor threshold location. The clinician then may determine the subject's treatment power level based on the subject's motor threshold level. A target anatomy of the subject's brain may be determined based on the disorder to be treated (e.g., using one or more algorithms corresponding to relationships between particular disorders and areas of the human brain known to be underactive or overactive for such disorders), and a desired position of the magnetic coil 116 relative to the target anatomy may be determined for directing magnetic stimulation at the target anatomy. The prescribing system 110 also may determine subject data for the subject. The subject data may include one or more subject identifiers associated with the subject. The subject identifiers may include, for example, a name of the subject, an identification number for the subject, or other information that may be used alone or in combination to uniquely identify the subject. In some instances, the prescribing system 110 may determine the subject data based on one or more indications of user input received from the user interface 132. The prescribing system 110 may cause the subject data and the stimulation parameter data to be stored in association with one another. In this manner, the association between the subject data and the stimulation parameter data may be used by the magnetic stimulation system 100 to ensure that treatment of the subject is administered in accordance with the stimulation parameter data for the subject. The subject data and the stimulation parameter data may be stored locally at the prescribing system 110. The subject data and the stimulation parameter data also may be provided to and stored at the data server 104 and/or the treatment system 140. The subject data and the stimulation parameter data may be stored and transmitted in an encrypted format to inhibit unauthorized access to the raw data.
In some embodiments, the prescribing system 110 may be used to generate or otherwise determine security data for the subject. The security data may include image data, audio data, and/or other types of data that may be used by the magnetic stimulation system 100 to determine or verify an identity of a subject. For example, the image recording device 117 of the prescribing system 110 may be used to capture one or more images of the subject and generate image data corresponding to the one or more images. Additionally or alternatively, the audio recording device 118 of the prescribing system 110 may be used to capture one or more audio recordings of the subject and generate audio data corresponding to the one or more audio recordings. In some embodiments, the prescribing system 110 may include other devices for generating other types of security data, such as retinal signature data or fingerprint data, which may be used for determining or verifying an identity of a subject. In some embodiments, the security data may be generated by another system separate from the prescribing system 110 and provided to the prescribing system 110, the data server 104, and/or the treatment system 140. In some embodiments, the security data may be generated by the treatment system 140 during initial setup and customization of the treatment system 140 for the subject and then provided to the prescribing system 110 and/or the data server 104. As described herein, the security data may be used by the treatment system 140 to determine whether the stimulation parameter data for the treatment system 140 is associated with a subject attempting to use the treatment system 140 (i.e., whether a subject is the intended subject for the treatment system 140), whether the headpiece 161 is associated with a subject attempting to use the headpiece 161 (i.e., whether a subject is the intended subject for the headpiece 161), and/or whether a verbal command received by the treatment system 140 is associated with a subject (i.e., whether a verbal command was made by the intended subject or another person).
After the stimulation parameter data for the subject has been determined using the prescribing system 110, the treatment system 140 may be setup and customized for the subject. Such setup and customization of the treatment system 140 may be performed at an equipment dispensary, which may be at the same clinical location as the prescribing system 110 or a different location. The headpiece 161 of the treatment system 140 may be configured for the intended subject. For example, the magnetic coil 146 may be positioned relative to the body 162 of the headpiece 161, and the secure locking means 164 may be used to mount the magnetic coil 146 at a fixed location relative to the body 162, with the fixed location corresponding to a pre-determined position of the headpiece 161 relative to the target anatomy of the subject. In this manner, when the headpiece 161 is at the pre-determined position relative to the target anatomy, the magnetic coil 146 is properly positioned to stimulate the target anatomy. Customization of the headpiece 161 for the subject also may include forming or affixing the headpiece identifier 165, with the headpiece identifier 165 being associated with the headpiece 161 and the subject.
At block 182 of the process flow 180, the treatment system 140 may receive the stimulation parameter data and first image data for the subject. In some embodiments, the stimulation parameter data and the first image data may be received by and stored at the treatment system 140 during setup and customization of the treatment system 140 for the subject. The subject data also may be received by and stored at the treatment system 140 in association with the stimulation parameter data and the first image data during setup of the treatment system 140. The first image data may correspond to one or more first images of at least a portion of the subject and at least a portion of the headpiece 161. For example, the one or more first images may include at least a portion of the subject's face and at least a front portion of the headpiece 161 including the headpiece identifier 165. The one or more first images may be captured while the headpiece 161 is at the pre-determined position relative to the target anatomy of the subject. In some embodiments, the one or more first images may be captured by the image recording device 147 of the treatment system 140. In some embodiments, the one or more first images may be captured by the image recording device 117 of the prescribing system 110, and the first image data may be provided to the treatment system 140. In some embodiments, the one or more first images may be captured by a system other than the prescribing system 110 and the treatment system 140, and the first image data may be provided to the treatment system 140. In some embodiments, the first image data also may be provided to and stored at the data server 104. As described herein, the first image data may be used by the treatment system 140 to determine whether the headpiece 161 is associated with a subject attempting to use the headpiece 161 (i.e., whether a subject is the intended subject for the headpiece 161), and/or whether the headpiece 161 is properly positioned on the head of the subject (i.e., whether the headpiece 161 is at the pre-determined position relative to the target anatomy of the subject). In this manner, the first image data may be used by the treatment system 140 as reference data for making such determinations. After the treatment system 140 has been configured for the subject, the subject may transport the treatment system 140 to a remote location relative to the prescribing system 110 for use. For example, the treatment system 140 may be taken to the subject's home or other location for convenient point-of-care use.
At block 183 of the process flow 180, the treatment system 140 may receive second image data for the subject. The second image data may correspond to one or more second images of at least a portion of the subject and at least a portion of the headpiece 161. The one or more second images may be captured prior to beginning a magnetic stimulation treatment session. The one or more second images may be captured by the image recording device 147 of the treatment system 140. As described above, during use of the treatment system 140, the subject may position the headpiece 161 on the subject's head while the subject is seated in a chair and faces the mirror 172, and the image recording device 147 may capture the one or more second images using the mirror 172. The one or more second images may include at least a portion of the subject's face and at least a front portion of the headpiece 161 including the headpiece identifier 165. As described herein, the second image data may be used by the treatment system 140 to determine whether the stimulation parameter data for the treatment system 140 is associated with a subject attempting to use the treatment system 140 (i.e., whether a subject is the intended subject for the treatment system 140), whether the headpiece 161 is associated with a subject attempting to use the headpiece 161 (i.e., whether a subject is the intended subject for the headpiece 161), and/or whether the headpiece 161 is properly positioned on the head of the subject (i.e., whether the headpiece 161 is at the pre-determined position relative to the target anatomy of the subject). In some embodiments, the second image data also may be provided to and stored at the data server 104 and/or the prescribing system 110.
At block 184 of the process flow 180, the treatment system 140 may use the first image data and the second image data to determine that the stimulation parameter data corresponds to the subject. In some embodiments, the treatment system 140 may compare the first image data and the second image data to determine that the stimulation parameter data corresponds to the subject. For example, the treatment system 140 may use one or more facial recognition algorithms to compare the first image data and the second image data and determine whether the subject is the intended subject associated with the stimulation parameter data. In some embodiments, one or more facial recognition algorithms may use the one or more first images to determine one or more facial characteristics of the intended subject and then may determine whether the one or more facial characteristics are present in the one or more second images. Various approaches may be used for analyzing the first image data and the second image data to determine whether the stimulation parameter data corresponds to the subject. In some embodiments, the treatment system 140 may enable operation of the stimulator 145 and/or the magnetic coil 146 based at least in part on the determination that the stimulation parameter data corresponds to the subject.
At block 185 of the process flow 180, the treatment system 140 may use the second image data to determine that the headpiece 161 corresponds to the subject. In some embodiments, the treatment system 140 may use the headpiece identifier 165 and the face of the subject in the one or more second images to determine that the headpiece 161 corresponds to the subject. In some embodiments, the treatment system 140 may use one or more object and facial recognition algorithms to determine whether the subject is the intended subject associated with the headpiece 161. Various approaches may be used for analyzing the second image data to determine whether the headpiece 161 corresponds to the subject. In some embodiments, the treatment system 140 may enable operation of the stimulator 145 and/or the magnetic coil 146 based at least in part on the determination that the headpiece 161 corresponds to the subject.
In some embodiments, the treatment system 140 may use the first image data and the second image data to determine whether the headpiece 161 is properly positioned on the head of the subject (i.e., whether the headpiece 161 is at the pre-determined position relative to the target anatomy of the subject). In some embodiments, the treatment system 140 may compare the first image data and the second image data to determine whether the headpiece 161 is at the pre-determined position. For example, the treatment system 140 may use one or more object and facial recognition algorithms to compare the first image data and the second image data and determine whether the headpiece 161 is at the pre-determined position. In some embodiments, one or more object and facial recognition algorithms may use the one or more first images to determine a position of the headpiece 161 relative to one or more facial features of the subject in the one or more first images and then may determine whether the headpiece 161 is similarly positioned relative to the one or more facial features of the subject in the one or more second images. Various approaches may be used for analyzing the first image data and the second image data to determine whether the headpiece 161 is at the pre-determined position. In some embodiments, the treatment system 140 may enable operation of the stimulator 145 and/or the magnetic coil 146 based at least in part on the determination that the headpiece 161 is at the pre-determined position. As described above, the treatment system 140 may cause the first indicator 166 to be activated based at least in part on the determination that the headpiece 161 is at the pre-determined position, thereby informing the subject that the headpiece 161 is at the pre-determined position. In some embodiments, the treatment system 140 may determine that the headpiece 161 is not at the pre-determined position. As described above, the treatment system 140 may cause one or more of the second indicators 167 to be activated based at least in part on the determination that the headpiece 161 is not at the pre-determined position, thereby informing the subject that the headpiece 161 is not at the pre-determined position and indicating a desired direction of movement (e.g., up, down, right, or left) of the headpiece 161 relative to the head of the subject to reach the pre-determined position.
In some embodiments, the treatment system 140 may determine whether the headpiece 161 is at the pre-determined position prior to beginning a treatment session and may monitor positioning of the headpiece 161 throughout the treatment session (i.e., while magnetic stimulation is being administered to the subject). In other words, the treatment system 140 may ensure that the headpiece 161 remains at the pre-determined position throughout the treatment session. For example, the treatment system 140 may periodically receive additional image data corresponding to one or more additional images of at least a portion of the subject and at least a portion of the headpiece 161 captured by the image recording device 147 during the treatment session. In some embodiments, the treatment system 140 may use the first image data and the additional image data to determine that the headpiece 161 is not at the pre-determined position during the treatment session (i.e., the headpiece 161 has moved away from the pre-determined position during the treatment session). In such instances, the treatment system 140 may cause operation of the stimulator 145 and/or the magnetic coil 146 to be paused or stopped based at least in part on the determination that the headpiece 161 is not at the pre-determined position. Further, the treatment system 140 may cause one or more of the second indicators 167 to be activated based at least in part on the determination that the headpiece 161 is not at the pre-determined position, thereby informing the subject that the headpiece 161 is not at the pre-determined position and indicating a desired direction of movement (e.g., up, down, right, or left) of the headpiece 161 relative to the head of the subject to reach the pre-determined position. The treatment system 140 may cause operation of the stimulator 145 and/or the magnetic coil 146 to be resumed based at least in part on a subsequent determination that the headpiece 161 is at the pre-determined position.
In some embodiments, the treatment system 140 may monitor a state of the subject (e.g., awake state, asleep state, seizure state, etc.) throughout a treatment session (i.e., while magnetic stimulation is being administered to the subject). In other words, the treatment system 140 may ensure that the subject remains in a desired state (e.g., awake state) throughout the treatment session and may respond accordingly in the event of onset of an undesired state (e.g., asleep state, seizure state, etc.) during the treatment session. For example, the treatment system 140 may periodically receive additional image data corresponding to one or more additional images of at least a portion of the subject captured by the image recording device 147 during the treatment session. In some embodiments, the additional image data may be the same image data used by the treatment system 140 for determining whether the headpiece 161 is at the pre-determined position during the treatment session. The treatment system 140 may use one or more facial recognition algorithms to determine a state of the subject based at least in part on the additional image data. Various approaches may be used for analyzing the additional image data to determine the state of the subject.
In some embodiments, the treatment system 140 may determine that the additional image data is indicative of an awake state (i.e., the subject is awake). In such instances, the treatment system 140 may cause operation of the stimulator 145 and the magnetic coil 146 to be maintained based at least in part on the determination that the state of the subject is the awake state. In some embodiments, the treatment system 140 may determine that the additional image data is indicative of an asleep state (i.e., the subject is asleep or falling asleep). In such instances, the treatment system 140 may cause operation of the stimulator 145 and/or the magnetic coil 146 to be paused or stopped based at least in part on the determination that the state of the subject is the asleep state. Further, the treatment system 140 may cause one or more alarms, such as visual, audible, or haptic alarms, of the treatment system 140 to be activated based at least in part on the determination that the state of the subject is the asleep state, thereby urging the subject to wake up. The treatment system 140 may cause operation of the stimulator 145 and/or the magnetic coil 146 to be resumed based at least in part on a subsequent determination that the state of the subject is the awake state. In some embodiments, the treatment system 140 may determine that the additional image data is indicative of a seizure state (i.e., the subject is experiencing a seizure). In such instances, the treatment system 140 may cause operation of the stimulator 145 and/or the magnetic coil 146 to be disabled or stopped based at least in part on the determination that the state of the subject is the seizure state. Further, the treatment system 140 may cause an emergency message indicative of the seizure state to be sent to the prescribing system 110, the supervising clinician user device 106, and/or the emergency response user device 108.
In some embodiments, the treatment system 140 may enable operation of the stimulator 145 and/or the magnetic coil 146 based at least in part on a determination that one or more stimulation conditions are met. For example, the treatment system 140 may enable operation of the stimulator 145 and/or the magnetic coil 146 based at least in part on a determination that one or more (in any combination), or all, of the following stimulation conditions are met: (i) the stimulation parameter data is associated with the subject; (ii) the headpiece 161 is associated with subject; (iii) the headpiece 161 is at the pre-determined position; and (iv) the state of the subject is the awake state.
In some embodiments, the treatment system 140 may change an operational state (e.g., off, on, paused, etc.) of the stimulator 145 based at least in part on one or more indications of interaction by the subject (or an assistant aiding the subject) with the user interface 171. The treatment system 140 may receive an indication of interaction by the subject with the user interface 171, with the indication of interaction being associated with an operational state that is different from a current operational state of the of the stimulator 145. For example, the treatment system 140 may cause the stimulator 145 to assume a first operational state (e.g., on state) and may subsequently receive an indication of interaction that is associated with a different second operational state (e.g., off state). In such instances, the treatment system 140 may cause the stimulator 145 to assume the second operational state based at least in part on the indication of interaction.
In some embodiments, the treatment system 140 may change an operational state (e.g., off, on, paused, etc.) of the stimulator 145 based at least in part on an audio recording of the subject that includes a verbal command (e.g., start, stop, pause, etc.). The treatment system 140 may receive audio data corresponding to one or more audio recordings of the subject, with the one or more audio recordings being indicative of a command associated with an operational state that is different from a current operational state of the of the stimulator 145. For example, the treatment system 140 may cause the stimulator 145 to assume a first operational state (e.g., on state) and may subsequently receive audio data corresponding to one or more audio recordings of the subject captured by the audio recording device 148, with the one or more audio recordings being indicative of a command associated with a different second operational state (e.g., off state). In such instances, the treatment system 140 may determine whether the received audio data is associated with the subject (i.e., whether the audio recording is of the intended subject). For example, the treatment system 140 may compare the received audio data with reference audio data for the subject to determine whether the received audio data is associated with the subject. In some embodiments, the treatment system 140 may determine that the received audio data is associated with the subject and may cause the stimulator 145 to assume the second operational state based at least in part on the determination that the received audio data is associated with the subject. In some embodiments, the treatment system 140 may determine that the received audio data is not associated with the subject (i.e., the audio recording is of a person other than the intended subject) and may cause the stimulator 145 to maintain the first operational state based at least in part on the determination that the received audio data is not associated with the subject. In this manner, the treatment system 140 may respond only to verbal commands by the intended subject and not verbal commands by other persons.
During a magnetic stimulation treatment session, the treatment system 140 may cause the stimulator 145 to generate a plurality of electric pulses and may cause the magnetic coil 146 to deliver magnetic stimulation to the subject. The treatment system 140 may cause the stimulator 145 to generate the plurality of electric pulses in accordance with the stimulation parameter data and may cause the magnetic coil 146 to deliver the magnetic stimulation to the subject in accordance with the stimulation parameter data. In some embodiments, the magnetic stimulation may be transcutaneous magnetic stimulation. In some embodiments, the magnetic stimulation may be transcranial magnetic stimulation. In some embodiments, the magnetic stimulation may be repetitive transcranial magnetic stimulation.
In some embodiments, the treatment system 140 may generate stimulation history data including one or more metrics associated with one or more stimulation sessions administered to the subject. For example, the treatment system 140 may generate stimulation history data after completion, or partial completion, of a stimulation session. In some embodiments, the treatment system 140 may send the stimulation history data, or otherwise cause the stimulation history data to be sent, to the prescribing system 110, the data server 104, and/or the supervising clinician user device 106. In this manner, the stimulation history data may be reviewed by the supervising clinician or other authorized persons to determine whether any modifications to the stimulation parameter data for the subject should be made. In some embodiments, the stimulation history data may be transmitted in an encrypted format to inhibit unauthorized persons from accessing the raw data.
In some embodiments, the treatment system 140 may receive new stimulation parameter data that is different, at least in part, from the initial stimulation parameter data received by the treatment system 140. In other words, the treatment system 140 may receive modifications or updates to the stimulation parameter data for the subject. In some embodiments, the treatment system 140 may receive new stimulation parameter data from the supervising clinician user device 106. For example, treatment system 140 may receive new stimulation parameter data from the supervising clinician user device 106 after sending stimulation history data or a request for updated stimulation parameter data to the supervising clinician user device 106. In some embodiments, the treatment system 140 may receive new stimulation parameter data from the prescribing system 110. For example, treatment system 140 may receive new stimulation parameter data from the prescribing system 110 after sending stimulation history data or a request for updated stimulation parameter data to the prescribing system 110. In some embodiments, the treatment system 140 may receive new stimulation parameter data from the data server 104. For example, treatment system 140 may receive new stimulation parameter data from the data server 104 after sending stimulation history data or a request for updated stimulation parameter data to the data server 104. In some embodiments, the new stimulation parameter data may be transmitted in an encrypted format to inhibit unauthorized persons from accessing the raw data. The treatment system 140 may determine that the new stimulation parameter data supersedes at least a portion of the initial stimulation parameter data, for example by comparing respective timestamps or status indicators associated with the new stimulation parameter data and the initial stimulation parameter data. In some embodiments, the treatment system 140 may cause the new stimulation parameter data to be stored locally at the treatment system 140 in association with the subject data and the first image data.
The treatment system 140 may be used to carry out a number of magnetic stimulation treatment sessions required by the treatment protocol for the subject. It will be appreciated that, in some embodiments, the operations described above with respect to blocks 181 and 182 of the process flow 180 may be carried out once for the subject, while the operations described above with respect to blocks 183, 184, and 185 of the process flow 180 may be carried out for each treatment sessions. After completion of the treatment protocol, the treatment system 140 may be turned in by the subject and reconfigured for use by a different subject.
