This disclosure relates generally to an ultrasound imaging system and method for controlling a plurality of light assemblies in order to selectively illuminate one or more a plurality of probe holders that are part of the ultrasound imaging system.
Ultrasound examinations are typically performed in rooms with the lights either dimmed down significantly or turned off to make it easier for the clinician to clearly see details in the images acquired by the ultrasound imaging system. The ultrasound probes are typically stored in probe holders along the sides of the ultrasound imaging system. Very little light from the display or the user interface reaches the probe holders. As a result, it can be difficult for a clinician to quickly and efficiently select the desired ultrasound probe for a given ultrasound protocol. Additionally, after using the ultrasound probe to perform the ultrasound examination, it can be difficult for the clinician to locate the appropriate probe holder for storing the ultrasound probe after the examination using conventional ultrasound imaging systems.
Additionally, some ultrasound imaging systems use sensors associated with each probe holder to detect when an ultrasound probe is in the probe holder and when the ultrasound probe associated with a particular probe holder is in use. For some of these ultrasound imaging systems it is important to make sure that each ultrasound probe is returned to its associated probe holder. Due to the low-light environment, it can be difficult for clinicians to locate the associated probe holder after performing an examination.
For at least the reasons discussed hereinabove, there is a need for an improved ultrasound imaging system and method for use with an ultrasound imaging system.
The above-mentioned shortcomings, disadvantages, and problems are addressed herein which will be understood by reading and understanding the following specification.

The ultrasound imaging system 100 also includes a processor 116 to control the transmit beamformer 101, the transmitter 102, the receiver 108, and the receive beamformer 110. The processor 116 is in electronic communication with the ultrasound probes (104, 105, 106). The processor 116 may control any one of the three ultrasound probes to acquire ultrasound data. The processor 116 controls which of the elements in the selected ultrasound probe are active and the shape of a beam emitted from the selected ultrasound probe. The ultrasound imaging system 100 may also include a touch screen 117 according to an embodiment. The touch screen 117 provides and input/output interface between the ultrasound imaging system 100 and a user. The processor 116 sends signals to the touch screen 117, causing the touch screen 117 to display visual outputs to the user, such as images, a graphical user interface (GUI), video clips, menus, or any other type of visual output. The touch screen 117 outputs signals to the processor 116 based on the touch inputs, which may be in the form of one or more touch gestures, received via the touch screen 117.
The touch screen 117 includes a touch-sensitive surface or layer configured to receive touch inputs from the user. The touch screen 117 in combination with the processor 116 converts one or more detected touch gestures into actions, commands, or interactions. In some embodiments, the touch gestures may interact with a GUI displayed on the touch screen 117. The user may interact with the touch screen 117 using one or more fingers and/or an object, such as a stylus.
The touch screen 117 may use any type of technology to display visual outputs including a light-emitting diode (LED) display, an organic light-emitting diode (OLED) display, a liquid crystal display (LCD), a variable graphics array (VGA), or any other type of apparatus configured for displaying an image. Other display technologies may be used in other embodiments.
The ultrasound imaging system 100 includes a display device 118 in electronic communication with the processor 116. The display device 118 may use any type of technology to display visual outputs including a light-emitting diode (LED) display, an organic light-emitting diode (OLED) display, a liquid crystal display (LCD), a variable graphics array (VGA), or any other type of apparatus configured for displaying an image. The display device 118 may also be configured to display graphical user interface (GUI) elements.
For purposes of this disclosure, the term “electronic communication” may be defined to include both wired and wireless connections. The processor 116 may include a central processor (CPU) according to an embodiment. According to other embodiments, the processor 116 may include other electronic components capable of carrying out processing functions, such as a digital signal processor, a field-programmable gate array (FPGA), or a graphic board. According to other embodiments, the processor 116 may include multiple electronic components capable of carrying out processing functions. For example, the processor 116 may include two or more electronic components selected from a list of electronic components including: a central processor, a digital signal processor, an FPGA, and a graphic board. According to another embodiment, the processor 116 may also include a complex demodulator (not shown) that demodulates the RF data and generates raw data. In another embodiment the demodulation can be carried out earlier in the processing chain. The processor 116 may be adapted to perform one or more processing operations according to a plurality of selectable ultrasound modalities on the data. The data may be processed in real-time during a scanning session as the echo signals are received. For the purposes of this disclosure, the term “real-time” is defined to include a procedure that is performed without any intentional delay. For purposes of this disclosure, the term “real-time” will be additionally defined to include an action occurring within 2 seconds. For example, if data is acquired, then a real-time display of that data would occur within 2 seconds. Those skilled in the art will appreciate that most real-time procedures or processes will be performed in substantially less time than 2 seconds. The data may be stored temporarily in a buffer (not shown) during a scanning session and processed in less than real-time in a live or off-line operation. Some embodiments of the invention may include multiple processors (not shown) to handle the processing tasks. For example, a first processor may be utilized to demodulate and decimate the RF signal while a second processor may be used to further process the data prior to displaying an image. It should be appreciated that other embodiments may use a different arrangement of processors.
The ultrasound imaging system 100 may continuously acquire data at a given frame-rate or volume-rate. Images generated from the data may be refreshed at a similar frame-rate or volume-rate. A memory 120 is included for storing processed frames of acquired data. In an exemplary embodiment, the memory 120 is of sufficient capacity to store at least several seconds worth of frames of ultrasound data. The frames of data are stored in a manner to facilitate retrieval thereof according to its order or time of acquisition. The memory 120 may comprise any known data storage medium.
The ultrasound imaging system 100 includes a plurality of probe holders: a first probe holder 150, a second probe holder 152, and a third probe holder 154. Each of the probe holders (150, 152, 154) defines a slot for allowing passage of a cable of the ultrasound probe according to an embodiment. For example, the first probe holder 150 defines a first slot 170, the second probe holder 152 defines a second slot 172, and the third probe holder 154 defines a third slot 174. Each of the sensor assemblies (i.e., the first sensor assembly 130, the second sensor assembly 132, and the third sensor assembly 134) may be configured to detect if an ultrasound probe (104, 105, or 106) is positioned in one of the probe holders (150, 152, 154). For example, the first sensor assembly 130 may be configured to detect if one of the ultrasound probes (104, 105, 106) is positioned in the first probe holder 150, the second sensor assembly 132 may be configured to detect if one of the ultrasound probes (104, 105, 106) is positioned in the second probe holder 152, and the third sensor assembly 134 may be configured to detect if one of the ultrasound probes (104, 105, 106) is positioned in the third probe holder 154.
Each of the ultrasound probes (104, 105, 106) may include a cable configured carry signals from the transmitter 102 and ultrasound data from the ultrasound probes (104, 105, 106). According to other embodiments, one of more of the ultrasound probes (104, 105, 106) may be wireless. Each of the sensor assemblies (130, 132, 134) may include one or more sensors capable of detecting the ultrasound probe of the passage of a cable that is part of the ultrasound probe. Each of the sensor assemblies (130, 132, 134) may include one or more sensors selected from the group including: a capacitive sensor, an electromagnetic sensor, an inductive proximity sensor, an optical sensor, or any other type of sensor configured to detect if an ultrasound probe is in one of the probe holders or if the cable has passed through a slot in the probe holder. According to an exemplary embodiment, each probe holder may include a slot for allowing passage of a cable attached to the ultrasound probe and the sensor assembly for each probe holder may be positioned to detect the passage of the probe cable through the slot. Once an association has been made between one of the ultrasound probes (104, 106, and 108) and one of the probe holders (150, 152, and 153), the processor 116 may determine if the associated ultrasound probe is in in a particular probe holder by tracking the number of times the probe cable has passed through the slot for a particular probe holder. For example, the processor 116 may track the ultrasound probe in a memory and toggle the status of the ultrasound probe between “in the ultrasound probe holder” and “out of the ultrasound probe holder.” The processor 116 may be further configured to adjust a probe status based on whether the ultrasound probe is detected to be “in the ultrasound probe holder” or “out of the ultrasound probe holder.” For example, the processor 116 may determine that the ultrasound probe is being used for active scanning based on whether or not the ultrasound probe is in the probe holder according to an embodiment.
The ultrasound imaging system 100 also includes a plurality of light assemblies. For example,
According to an embodiment, each of the light assemblies (140, 142, and 144) may include to ability to provide light of two or more different colors to illuminate the respective probe holder with two or more different colors. For example, each of the light assemblies may include LEDs, OLEDs or incandescent bulbs of two or more different colors. According to another embodiment, each of the light assemblies (140, 142, and 144) may include a red element, a green element, a blue element and a white element in order to allow for the generation of any desired color by controlling the relative contributions of the red element, the green element, the blue element and a white element. According to an exemplary embodiment, each of the light assemblies (140, 142, 144) may include a red LED as the red element, a green LED as the green element, a blue LED as the blue element, and a white LED as the white element. According to another exemplary embodiment, each of the light assemblies (140, 142, 144) may include a red OLED as the red element, a green OLED as the green element, a blue OLED as the blue element, and a white OLED as the white element.
Optionally, embodiments of the present invention may be implemented utilizing contrast agents. Contrast imaging generates enhanced images of anatomical structures and blood flow in a body when using ultrasound contrast agents including microbubbles. After acquiring data while using a contrast agent, the image analysis includes separating harmonic and linear components, enhancing the harmonic component, and generating an ultrasound image by utilizing the enhanced harmonic component. Separation of harmonic components from the received signals is performed using suitable filters. The use of contrast agents for ultrasound imaging is well-known by those skilled in the art and will therefore not be described in further detail.
In various embodiments of the present invention, data may be processed by other or different mode-related modules by the processor 116 (e.g., B-mode, color Doppler, M-mode, color M-mode, spectral Doppler, Elastography, TVI, strain, strain rate, and the like) to form 2D or 3D data. For example, one or more modules may generate B-mode, color Doppler, M-mode, color M-mode, spectral Doppler, Elastography, TVI, strain, strain rate and combinations thereof, and the like. The image beams and/or frames are stored, and timing information indicating a time at which the data was acquired in memory may be recorded. The modules may include, for example, a scan conversion module to perform scan conversion operations to convert the image frames from beam space coordinates to display space coordinates. A video processor module may be provided that reads the image frames from a memory, such as the memory 120, and displays the image frames in real time while a procedure is being carried out on a patient. A video processor module may store the image frames in an image memory, from which the images are read and displayed.
In
The processor 116 is configured to control the plurality of light assemblies (140, 142, and 144) in order to selectively illuminate one or more of the plurality of probe holders (150, 152, and 154). The processor 116 may be configured to control the plurality of light assemblies (140, 142, and 144) in order to illuminate one or more of the plurality of probe holders with a single color of light and/or the processor 116 may be configured to control the plurality of light assemblies (140, 142, and 144) in order to illuminate one or more of the plurality of probe holders using different colors of light.
At step 602, the processor 116 receives a probe status. The probe status may be one of activated, actively scanning, or inactive. The probe status may be probe diagnostics test in progress. For embodiments involving an probe diagnostics test, the probe status may additionally include passed and failed.
At step 602, the processor 116 may receive the probe status automatically, such as after the selection of a protocol, or the probe status may by manually inputted through the user input device 115.
After receiving the probe status, the method 600 advances to step 604, where the processor 116 controls the plurality of light assemblies to illuminate one of the more of the probe holders (150, 152, 154). According to an embodiment where the probe status is “activated,” the processor 116 may control the plurality of light assemblies to illuminate the probe holder associated with the ultrasound probe that has been activated in order to help the clinician identify which of the plurality of ultrasound probes to use for a specific procedure. According to an embodiment where the probe status is “probe diagnostics test in progress,” the processor 116 may control the plurality of light assemblies to illuminate, with a first color, the probe holder associated with the ultrasound probe undergoing the probe diagnostics test. For example, the first color may be orange. According to an embodiment, the processor 116 may control the plurality of light assemblies to illuminate the probe holder associated with the ultrasound probe with a pattern such as a flashing pattern or a strobing pattern.
The processor 116 may control the plurality of light assemblies to illuminate the probe holder associated with the ultrasound probe with a second color to indicate that the ultrasound probe has passed the probe diagnostics test or the processor 116 may control the plurality of light assemblies to illuminate the probe holder associated with the ultrasound probe with a third color to indicate that the ultrasound probe has failed the probe diagnostics test. According to an embodiment, the first color may be green to indicate the ultrasound probe has passed the probe diagnostics test and the second color may be red to indicate the ultrasound probe has failed the probe diagnostics test. Those skilled in the art should appreciate that different colors may be used according to various embodiments.
According to an embodiment, the processor 116 may receive an updated probe status after step 604. Updated probe statuses could include “inactive”, and/or a different ultrasound probe could be activated. The processor 116 may be configured to illuminate one of the probe holders.
According to another embodiment the processor 116 may control the plurality of light assemblies to illuminate the probe holder associated with an ultrasound probe that has been removed from one of the probe holders (150, 152, 154) to actively scan the patient (i.e., according to an embodiment where the probe status is “actively scanning”). According to an exemplary embodiment, the processor 116 may control the plurality of light assemblies in response to receiving a signal from one of the sensor assemblies (130, 132, 134) indicating that the ultrasound probe has been removed from its respective probe holder. Illuminating the one of the plurality of probe holders (150, 152, 154) from which the ultrasound probe has been removed provides the user with a clear indication of the position to which the ultrasound probe should be returned after scanning. According to an embodiment, the processor 116 may control the plurality of light assemblies to no longer illuminate the probe holder associated with the ultrasound probe that was used to actively scan the patient after the ultrasound probe has been returned to its respective probe holder. This may also be determined based on a signal from one of the sensor assemblies (130, 132, 134). For example, if the first ultrasound probe 104 is removed from the first probe holder 150, the processor 116 may control the plurality of light assemblies to illuminate the first probe holder 150 while the first ultrasound probe 104 is being used to actively scan the patient. Then, once the first ultrasound probe 104 has been returned to the first probe holder 150, the processor 116 may control the plurality of light assemblies to no longer illuminate the first probe holder. According to anther embodiment, the processor 116 may be configured to change the color used to illuminate the first probe holder, for instance, in order to indicate that the status of the first ultrasound probe 104 is “actively scanning.” According to other embodiments, the processor 116 may be configured to control the illumination of other ones of the plurality of probe holders to indicate that a different ultrasound probe is being used to actively scan the patient.
At step 702, a selection of a protocol is received by the processor 116. The selection of the protocol may be in response to a input through the user input device 115, or the processor 116 may receive a selection of the protocol automatically as either a default setting for the ultrasound imaging system or for embodiments where the protocol is part of a larger workflow that was previously manually selected.
At step 704, the processor 116 activates the appropriate ultrasound probe for the selected protocol. Each protocol is ideally performed with a specific ultrasound probe or an ultrasound probe of a specific type based on factors such as the size and shape of the probe head, the type of array, the frequency of the ultrasound probe, and/or the number of elements in the array. According to an embodiment, the processor 116 may be configured to select the one of the plurality of ultrasound probes (104, 105, 106) that would be the most well-suited for the selected protocol. The method 700 will be described hereinafter with respect to an embodiment where the first ultrasound probe 104 is the most appropriate for the selected protocol, but according to other embodiment, the second ultrasound probe 105, the third ultrasound probe 106 or an additional ultrasound probe not shown in
As discussed hereinabove, each of the ultrasound probes (104, 105, 106) is associated with one of the plurality of probe holders (150, 152, 154). According to the embodiment shown in
At step 706, the processor 116 controls the plurality of light assemblies to illuminate the probe holder associated with the appropriate ultrasound probe. As discussed above, for an embodiment where the first ultrasound probe 104 is the appropriate ultrasound probe and the first ultrasound probe is associated with the first probe holder 150, the processor 116 will control the plurality of light assemblies to illuminate the first probe holder 150 with a first color. According to an embodiment, the first color may be red. The first color may be any other color according to various embodiments. Due to the illumination of the first probe holder 150, it is very easy for the clinician to see the location of the appropriate ultrasound probe for the current protocol.
At step 708, the clinician removes the first ultrasound probe 104 from the first ultrasound probe holder 150. The processor 116 receives a signal from the first sensor assembly 130 in response to the clinician removing the first ultrasound probe 104 from the first ultrasound probe holder 150. After receiving the signal from the first sensor assembly 130, at step 710, the processor 116 controls the plurality of light assemblies (140, 142, 144) to illuminate the first probe holder 150 with a second color that is different than the first color to indicate that the clinician is actively scanning with the first ultrasound probe 104. According to an exemplary embodiment, the second color may be green to indicate that the first ultrasound probe 104 is being used for scanning.
After completing the scanning of the patient, the clinician returns the first ultrasound probe 104 to the first probe holder 150 at step 712. In response to receiving a signal from the first sensor assembly 130 indicating that the first ultrasound probe 104 has been returned to the first probe holder 104, at step 714, the processor 116 controls the plurality of light assemblies to illuminate the first probe holder 150 with the first color to indicate that the first ultrasound probe 104 is still active, but that it is not being used for active scanning. According to other embodiments, the processor 116 may be configured to turn off the illumination for the first probe holder after the clinician returns the first ultrasound probe 104 to the first probe holder 150.
At step 802, the processor 116 receives a selection of a probe diagnostics test. According to an embodiment, the processor 116 may be configured to receive the selection of the test automatically or in response to receiving an input through the user input device 115. According to some embodiments, the processor 116 may be configured to automatically initiate the probe diagnostics test after a predetermined amount of time, a predetermined number of scans, or every time the ultrasound imaging system is turned on.
At step 803, the processor 116 is configured to initiate the probe diagnostics test in response to receiving the selection of the probe diagnostics test at step 802.
At step 804, the processor 116 is configured to control the plurality of light assemblies to illuminate the one of the plurality of probe holders (150, 152, 154) associated with the ultrasound probe being tested. The method 800 will be described according to an embodiment where the probe diagnostics test is being performed on the second probe 105 that is associated with the second probe holder 152. Therefore, according to an exemplary embodiment, at step 804, the processor 116 is configured to control the plurality of light assemblies to illuminate the second probe holder 152 with a first color at step 804. According to an embodiment, the first color may be orange. The first color may be any other color according to various embodiments. The processor 116 may further control the plurality of light assemblies to illuminate the second probe holder 152 in a flashing or strobing pattern to indicate that the probe diagnostics test is being performed.
At step 808, the method 800 advances to step 810 if the second ultrasound probe 105 passes the probe diagnostics test and the method 800 advances to step 812 if the second ultrasound probe 105 fails the probe diagnostics test.
At step 810, the processor 116 controls the plurality of light assemblies to illuminate the second probe holder 152 with a second color to indicate that the second ultrasound probe 105 passed the probe diagnostics test. According to an embodiment, the second color may be green to indicate that the second ultrasound probe 105 passed the probe diagnostics test. The second color may be any other color according to various embodiments.
At step 812, the processor 116 controls the plurality of light assemblies to illuminate the second probe holder 152 with a third color to indicate that the second ultrasound probe 105 failed the probe diagnostics test. According to an embodiment, the third color may be red to indicate that the second ultrasound probe 105 failed the probe diagnostics test. The third color may be any other color according to various embodiments.
While the method 800 was described according to an embodiment where the probe diagnostics test was performed on the second ultrasound probe 105, it should be appreciated that the method 800 may be performed on any of the ultrasound probes, including the first ultrasound probe 104 or the second ultrasound probe 105. For embodiments where the probe diagnostics test is performed on the first ultrasound probe 104, the processor 116 will control the illumination of the first probe holder 150. For embodiments where the probe diagnostics test is performed on the third ultrasound probe 104, the processor 116 will control the illumination of the third probe holder 154. Additionally, it should be appreciated that different colors may be used for the first color, the second color, and/or the third color according to various embodiments.
