1. Field of Invention
In general, the inventive arrangements relate to medical imaging systems, and more specifically, to combining medical imaging systems, such as, for example, providing an ultrasound docking port on a non-ultrasound medical imaging system.
2. Description of Related Art
For illustrative, exemplary, representative, and non-limiting purposes, preferred embodiments of the inventive arrangements will be described in terms of medical imaging systems. For example, common medical imaging systems include medical equipment for radiology, functional imaging, molecular imaging, vascular imaging, fluoroscopy, angiography, mammography, neurology, oncology, radio pharmacology, x-ray, nuclear medicine (NM), magnetic resonance imaging (MRI), positron emission tomography (PET), computed tomography (CT), ultrasound, and/or the like. However, the inventive arrangements are not limited in these regards.
Now then, in multi-modality medical imaging systems, various imaging techniques can be combined to acquire patient images. For example, in a PET/CT imaging system, imaging from both modalities can be combined to enhance patient imagery. While one such system can capture functional imagery, the other can capture anatomical imagery, with each enhancing and/or complementing the other. However, most medical imaging systems are not well-equipped to readily accommodate additional modality imaging systems, and successful fusion thereof remains desirable—e.g., progress has been made in image registration between modalities, but little less.
Thus, continued progress remains desirable for combining many attributes of multi-modality medical imaging systems. For example, it remains desirable to provide many medical imaging systems with a convenient ultrasound docking port, particularly as ultrasound equipment and/or systems become more portable, ubiquitous, useful, and/or practical, as a desirable add-in to numerous other imaging modality applications.
In various embodiments, multi-modality medical imaging systems and methods combine and/or fuse ultrasound medical imaging systems and non-ultrasound medical imaging systems, particularly via a docking port carried on, and/or otherwise supported by, the non-ultrasound medical imaging system so as to receive the ultrasound medical imaging system. The ultrasound medical imaging system and non-ultrasound medical imaging system can communicate directly, indirectly, and/or wirelessly.
When they are joined, each system can be configured for cross-imaging in the other modality. Each system can also be configured to display medical imagery from the other modality on respective and/or combined displays. Each system can also be configured to be controlled by a user interface on the other system and/or a common user interface. Registry between patient imagery is provided, as is improved workflow between the systems.
A clear conception of the advantages and features constituting inventive arrangements, and of various construction and operational aspects of typical mechanisms provided by such arrangements, are readily apparent by referring to the following illustrative, exemplary, representative, and non-limiting figures, which form an integral part of this specification, in which like numerals generally designate the same elements in the several views, and in which:
Referring now to the figures, preferred embodiments of the inventive arrangements will be described in terms of medical imaging systems. However, the inventive arrangements are not limited in this regard. For example, while variously described embodiments may provide ultrasound docking techniques in other imaging modality contexts, other applications are also hereby contemplated, including various other consumer, industrial, radiological, and inspection systems, and/or the like.

In any event, the transmitted ultrasonic signals are back-scattered from the object, such as from blood cells or muscular tissue within a body, to produce echo signals that return to the transducers 112. These echo signals are then received by a receiver 116 in communication with the transducers 112. These echo signals are then passed from the receiver 116 to a beamformer 118, which performs beamforming and outputs RF signal data therefrom. The RF signal data then passes from the beamformer 118 to an RF processor 120. In an optional embodiment, the RF processor 120 may also include a complex demodulator (not shown) that demodulates the RF signal data to form IQ data pairs that represent the echo signals. Either the RF signal data or IQ data pairs are then routed from the RF processor 120 to a RF/IQ buffer 122 for temporary storage. A user interface 124 can also be used to control operation of the ultrasound system 108, including, for example, controlling input of patient data, changing a scanning or display parameter, and/or the like.
Preferably, the ultrasound system 108 also includes a processor 126 to process the acquired ultrasound information (e.g., the RF signal data or IQ data pairs) from the RF/IQ buffer 122 and prepare frames of ultrasound information for display on a display 128. Preferably, the processor 126 is configured to perform one or more processing operations according to selectable functions performed on the acquired ultrasound information. For example, the acquired ultrasound information can be processed in real-time during a scanning session as the echo signals are received; additionally, and/or alternatively, the acquired ultrasound information can also be stored temporarily in the RF/IQ buffer 122 (or other) during a scanning session, and then processed in other than real-time in a live or off-line operation.
In a preferred embodiment, the ultrasound system 108 continuously acquires ultrasound information at a frame rate in excess of, for example, fifty frames per second, which is approximately the perception rate of the human eye. Thus, the acquired ultrasound information can be displayed on the display 128 at a slower frame-rate. Accordingly, a memory 130 can be provided between the processor 126 and the display 128 for storing processed frames of the acquired ultrasound information that are not yet ready and/or needed for immediate display on the display 128. In an exemplary embodiment, for example, the memory 130 is of sufficient capacity to store at least several seconds worth of processed frames of the acquired ultrasound information. Preferably, these frames of information are stored in a manner that facilitates their later retrieval according to an order and/or time and/or other of acquisition. In any event, the memory 130 may comprise any known data storage medium.
In addition, the processor 126 may also contain therewithin, and/or otherwise communicate with and/or control, a multi-modality detection module 132, which may be implemented in hardware, software, and/or any combination(s) thereof. More specifically, the multi-modality detection module 132 can be configured to receive signals from the user interface 124 through the processor 126, and it is particularly configured to recognize the presence and/or absence of the first medial imaging system 100. Alternatively, and/or additionally, the multi-modality detection module 132 may also be contained within and/or supported by the first medical imaging system 100 as well, in which it is configured to recognize the presence and/or absence of the second medial imaging system 104. It allows the medical imaging systems 100, 104 to recognize the presence and/or absence of one another.
Preferably, the multi-modality detection module 132 is configured to transfer information to a multi-modality mapping module 134, which is in communication with the memory 130 and/or remote therefrom. In any event, the multi-modality mapping module 134 may also be implemented in hardware, software, and/or any combination(s) thereof, and it may be implemented by the first medical imaging system 100 and/or second medical imaging system 104. It allows the medical imaging systems 100, 104 to map functions thereof based on received signals therefrom. The image detection and/or image mapping may change based on the state of the overall multi-modality medical imaging system—i.e., the first medical imaging system 100 and/or second medical imaging system 104.

In any event, operation of the sub-module routines is preferably controlled by the 126 processor and/or the like. More specifically, the sub-module routines 152-168 preferably perform mid-processor operations. For example, the processor 126 communicates ultrasound data 150 in one of several forms, such as IQ data pairs representing real and/or imaginary components associated with various data samples. The IQ data pairs can then be provided to one or more of a color flow module 152, power Doppler module 154, B-mode module 156, spectral Doppler module 158, and/or M-mode module 160. Optionally, other modules may also be included, such as a tissue Doppler module 162, strain module 164, strain rate module 166, and/or Acoustic Radiation Force Impulse (ARFI) module 168. The tissue Doppler module 162, strain module 164, and strain rate module 166 may, for example, together define an echocardiographic (ECG) processing configuration.
Preferably, each of the sub-module routines 152-168 are configured to process the IQ data pairs in a corresponding manner to respectively generate, for example, color-flow data 170, power Doppler data 172, B-mode data 174, spectral Doppler data 176, M-mode data 178, tissue Doppler data 180, strain data 182, strain rate data 184, and/or ARFI data 186, all of which may be stored in a memory 188, such as the memory 130 of
In addition, a scan converter module 190 can access vector data values associated with an image frame and convert the vector data values into Cartesian coordinates to generate an ultrasound image frame 192, particular formatted for display on the display 128 (see

In an embodiment of direct communication, the first medical imaging system 100 is configured with a docking station 140 to physically receive the second medical imaging system 104, thereby enabling transmissions therebetween. For example, with one suitable physical arrangement, the first medical imaging system 100 contains a receiving receptacle, such as, e.g., the docking station 140, into which the second medical imaging system 104 is received. This particular arrangement allows securing and/or releasably securing the first medical imaging system 100 and second medical imaging system 104 together.
In an embodiment of indirect and/or wireless communication, the first medical imaging system 100 is configured with a first wireless transmitter and/or receiver 136, and the second medical imaging system 104 is likewise configured with a second wireless transmitter and/or receiver 138, thereby enabling transmissions therebetween.
As such, the first medical imaging system 100 can display medical imaging information therefrom on a display 142 in communication therewith, as can the second medical imaging system 104 display medical imaging information therefrom on its display 128 in communication therewith. As needed and/or desired, however, the first medical imaging system 100 can also display medical imaging information on the display 128 of the second medical imaging system 104, as can the second medical imaging system 104 also display medical imaging information on the display 142 of the first medical imaging system 100. These images can also be displayed thereon in any suitable fashion, and the displays 128, 142 can also form and/or be a part of a singular and/or plural common display arrangement. In addition, one medical imaging system 100, 104 can be used to determine a region of interest, for example, while the other medical imaging system 100, 104 images thereabout.
In addition, as the second medical imaging system 104 includes an ultrasound probe 114 to emit ultrasonic signals into an object such as a body (not shown), so can the first medical imaging system 100 also contain an ultrasound probe 144. Accordingly, the ultrasound probes 114, 144 can either be fixed and/or docked to either the first medical imaging system 100 and/or second medical imaging system 104. As such, ultrasound images can be gathered by either or both of the first medical imaging system 100 and/or second medical imaging system 104, which can again be suitably displayed on the displays 128, 142. Processing power and/or other functionality can also be similarly shared therebetween the medical imaging systems 100, 104.
As such, the first medical imaging system 100 can operate and perform as an ultrasound imaging system, particularly when in communication with the second medical imaging system 104. Of course, the second medical imaging system 104 can also operate and perform as an ultrasound imaging system, including when in communication in with the first medical imaging system 100. Accordingly, the first medical imaging system 100 and second medical imaging system 104 are brought together and/or fused, both operationally and/or functionally.
In addition, when the first medical imaging system 100 operates in its traditional non-ultrasound imaging mode and the second medical imaging system 104 operates in its traditional ultrasound imaging mode, imagery therefrom can also be fused, including registering the imagery therebetween. In this context, registering imagery refers, for example, to bringing the geometries and/or coordinate systems of the imaged object together in a defined relationship, as between the first medical imaging system 100 and/or second medical imaging system 104. Accordingly, ultrasound data can be merged with before or after acquired images from other imaging modalities, such as the first medical imaging system 100, including both in real-time and/or delayed imagery. As such, imaging and/or other comparisons can be made while taking advantage of the respective strengths of each imaging modality. These comparisons can be either side-by-side on one or the other or both of the displays 128, 142, and/or by overlaying the images from the first medical imaging system 100 and/or second medical imaging system 104. It can also be done in real-time and/or sometime afterwards.
In addition, as the second medical imaging system 104 includes a user interface 124 to interface therewith, the first medical imaging system 100 also includes a user interface 146 to interface therewith. In addition, the first medical imaging system 100 can be controlled by the user interface 124 of the second medical imaging system 104, while the second medical imaging system 104 can also be controlled by the user interface 146 of the first medical imaging system 100. In addition, the user interfaces 124, 146 can also form and/or be a part of a singular and/or plural user interface. When the medical imaging systems 100, 104 are connected, one of the user interfaces 124, 146 and/or displays 128, 142 can also control and/or dominate the other respective user interface 124, 146 and/or displays 128, 142.
It can be noted, for example, that while providing and/or operating a separate first medical imaging system 100 and/or separate second medical imaging system 104 will ordinarily require multiple operators (not shown) and/or a single operator (not shown) to separately control each system 100, 104 individually, this can result in, for example, medical errors due to incorrect or improper data input, delays when moving patients (not shown) between systems 100, 104, etc. However, with the inventive arrangements, on the other hand, these problems can be minimized and/or overcome. Exam time can be decreased, yet improved medical care is provided. A single work flow (and/or single work list for a single patient) is thereby provided across a multi-modality platform.
Since the first medical imaging system 100 and second medical imaging system 104 are in communication with one another through the direct connection 208, 308 and/or indirect and/or wireless connection 210, 310, each system 100, 104 preferably detects the other system 100, 104 when they are working and/or functioning in tandem. For example, a manual operation on either the first medical imaging system 100 and/or second medical imaging system 104 could be used to determine the presence of the other system 100, 104, as well as could a periodic polling configuration, as needed and/or desired, as well as via the direct connection 208, 308 through the docking station 140 and/or the like. Accordingly, the multi-modality detection module 132 and/or multi-modality mapping module 134 (see
Automatic protocol configurations can also be generated based on system configurations, including, for example, the number, type, etc. of ultrasound probes 114, 144 each system 100, 104 is using. In addition, automatic synchronization of patient data and/or images from the first medical imaging system 100 and/or second medical imaging system 104 can also be provided, and multi-modality images can be gathered in a single patient examination from a single, combined imaging platform.
In accordance with all of the foregoing, technical effects include providing medical imaging systems and methods containing dedicated ultrasound docking ports. More specifically, ultrasound medical imaging systems and non-ultrasound medical imaging systems are combined and/or configured for communicating with one another via a docking port provided on, and/or otherwise supported by, the non-ultrasound medical imaging system, which is particularly outfitted and/or configured to receive the ultrasound medical imaging system. Medical patient workflows and/or imagery, in particular, are thereby enhanced.

Accordingly, the scope of the inventive arrangements are not limited to any of these embodiments. Rather, various details and features of the embodiments were disclosed as required.
