Patent Application
20170055952
The following generally relates to ultrasound imaging and more particular to a touch panel, of an ultrasound imager, with user interactive touch sensitive worksheet region and a controls region for concurrent assessment documenting, and ultrasound imager control.
Some clinical applications for ultrasonography, such as emergency medicine (EMED), require performing a fast diagnostic imaging procedure on a patient and subsequently reporting the findings as quickly as possible. The reporting has been through formal reports and worksheets. Formal reports are produced by the machine that includes measurements and possibly physician's diagnosis, and worksheets generally are informal reports, which are filled in by the technician (sonographer) to be later reviewed by the physician to make the physician aware of the technician's assessment of the scan. An example of a sub-portion of a worksheet from a 2011 ACEP (American College of Emergency Physicians) guideline is shown in
In applications such as EMED, the speed at which the diagnosis is performed can be critical for treating the patient effectively and managing the queue of patients in the emergency facility. In current practice, the clinician either performs an ultrasound examination and then retrieves and fills in the worksheet (sequential workflow) or pauses an ongoing ultrasound examination and partially fills in the worksheet as needed (interlaced workflow). Furthermore, with a paper worksheet, the clinician may manually hand draw a diagram of the scanned anatomical tissue or organ on the paper and mark a location of tissue of interest such as a suspected lesion on the anatomical drawing.
With the former approach, the clinician, after the examination, moves to a reporting area and has to re-visit images already observed and may not remember an earlier observation. Furthermore, the clinician has to spend added time outside of the actual examination to create the report, which delays diagnosis. With the latter, moving back and forth between the examination and a worksheet increases examination time, which delays diagnosis, and the clinician has to keep track of what has been performed so that a particular image is not missed or acquired more than once.
Aspects of the application address the above matters, and others.
In one aspect, a method includes concurrently activating a worksheet region and a controls region of a touch sensitive user interface. The worksheet region visually displays a digital worksheet form with fields editable through touch sensitive areas of the worksheet region. The controls region visually displays at least one control that controls at least one of scanning by an ultrasound imager and an ultrasound imager parameter of the ultrasound imager. The concurrently activated worksheet and controls regions are concurrently present on the touch sensitive user interface. The method further includes receiving a signal indicating the at least one control of the controls region is selected through a touch on a touch sensitive area of the controls region corresponding to the control while maintaining the activation of both the concurrently present worksheet and controls regions. The method further includes controlling, in response to the signal, the at least one of the scanning by the ultrasound imager and the ultrasound imager parameter of the ultrasound imager while maintaining the activation of both the concurrently present worksheet and controls regions. The method further includes receiving a first input at an editable field of the digital worksheet form in the worksheet region while maintaining the activation of both the concurrently present worksheet and controls regions. The method further includes entering the first input into the editable field, which transforms and constructs an updated digital worksheet form while maintaining the activation of both the concurrently present worksheet and controls regions. Those skilled in the art will recognize still other aspects of the present application upon reading and understanding the attached description.
In another aspect, an ultrasound imaging system includes circuitry configured to control ultrasound transducer element excitation and echo reception by an ultrasound transducer of the imaging system, processing of received echoes, and ultrasound image display. A user interface with a touch sensitive region, which includes at least a worksheet region and a controls region, wherein the worksheet region is configured to visually display a digital worksheet form with fields editable through touch sensitive areas of the worksheet region, and the controls region is configured to display at least one touch sensitive soft control, and wherein the worksheet region and the controls region are concurrently present on the touch sensitive region. A user interface controller configured to control the touch sensitive region, including forms displayed in the worksheet region and controls displayed in the controls region and generating signals in response to sensing activation of a touch sensitive area of at least one of a displayed form in the worksheet region and a displayed control in the controls region, and further configured to concurrently activate the worksheet region and the controls region so that the editable digital worksheet form is editable in the worksheet region concurrently while the at least one touch sensitive soft control is selectable in the controls region.
In another aspect, a method includes visibly presenting a touch sensitive worksheet region on a user interface, wherein the worksheet region visually displays a digital worksheet form with fields editable through touch sensitive areas of the worksheet region, receiving an edit input at a location over a sub-portion of a visually displayed graphical representation of anatomy of interest in the worksheet region, and displaying selected graphical indicia at the location in response to receiving the edit input at the location.
The application is illustrated by way of example and not limitation in the figures of the accompanying drawings, in which like references indicate similar elements and in which:
The ultrasound imaging system 202 includes a probe 204 with a one-dimensional (1D) or two-dimensional (2D) transducer array 206 with at least one transducer element. Suitable array configurations include, but are not limited to, linear, curved (e.g., concave, convex, etc.), circular, etc., full populated or sparse, etc. The probe 204 further includes a console interface 208, which may include a physical connector (e.g., an electro-mechanical device for joining electrical circuits) and/or wireless transceiver.
The ultrasound imaging system 202 further includes a display monitor 210. The display monitor 210 can be a cathode ray tube (CRT), a liquid crystal display (LCD), a light emitting diode (LED), and/or other display monitor. The display monitor 210 includes at least one image display area 212 configured to display at least one image 214. The display monitor 210 further includes a console interface 216, which may include a physical connector (e.g., an electro-mechanical device for joining electrical circuits) and/or wireless receiver.
The ultrasound imaging system 202 further includes a console 218. The console 218 houses components (not visible) such as transmit and receive circuitry that controls excitation of the at least one transducer element and detection of echoes with the at least one transducer element, a beamformer that processes signals indicative of the detected echoes and creates scanlines, a scan converter that converts the beamformed data to data viewable via the monitor 210, a processor (cpu, microprocessor, controller, etc.) and/or other components such as those for Doppler, flow velocity, etc. processing.
The console 218 further includes a user interface 220. The user interface 220 includes at least a touch sensitive region 222 with a touch sensitive surface. In the illustrated example, the user interface 220 further includes physical (“hard”) controls such as one or more knobs 224, dials 226, buttons 228, trackball 230, and/or other physical controls. Other user interface features may include visual indicators (e.g., lights, etc.), audible indicators (e.g., speakers, etc.), tactile indicators (e.g., a rough surface, a recess, etc.), and/or other indicators.
The touch sensitive region controls and/or the physical controls may include a time-gain control (TGC), a mode selection control (e.g., 2D, 3D, 4D, pulse wave (PW) Doppler, Color (Col) Doppler, M, etc.), a CINE control, a measurement control, a parameter control (e.g., zoom, a depth, focus, etc.), etc. For the touch sensitive region 222, a location of one or more of the controls may be moveable within the region, a visibility of the one or more of the controls within the region may be selectively, controls can be grouped together, etc.
As described in greater detail below, the touch sensitive region 222 at least includes a display workspace 232 for, e.g., selecting and/or entering information in a digital worksheet displayed in the workspace 232, and one or more soft or touch controls 234, where the digital worksheet displayed in the workspace 232 and the one or more soft or touch controls are concurrently active such that the digital worksheet can be edited and/or modified in the workspace 232 while an active control controls scanning and/or an ultrasound parameter.
The touch sensitive region 222 may include a resistive, a capacitive, etc. region. Furthermore, the touch sensitive region 222 may include a LCD, thin film transistor (TFT) LCD, organic LED (OLED), and/or other technology. Examples of suitable user interfaces include, but are not limited to, PCT/IB2014/066363, entitled “Ultrasound Imaging System Touch Panel with Multiple Different Clusters of Controls,” and filed Nov. 26, 2014, and PCT/IB2014/066365, entitled “Ultrasound Imaging System Touch Panel Cluster Control Interaction,” and filed Nov. 26, 2014, the entireties of which are incorporated herein by reference.
The console 218 further includes a probe interface 236 and a display monitor interface 238, which respectively are complementary to the console interfaces 208 and 216. For example, the probe interface 236 is complementary to the console interface 208, and, in the illustrated example, are in electrical communication via a cable 240 connected there between. The cable 240 is fixedly attached to the console interface 208 and removeably attached to the probe interface 236, which may be through female and male connectors that physically engage and physically connect electrodes.
In this example, the ultrasound imaging system 202 includes a mobile mechanical support 242 with a monitor support 244, a console support 246, and a base 248 with movers 250 such as one or more wheels, casters, etc. The monitor 210 is attached to the monitor support 244 and the console 218 is attached to the console support 246. A probe support 252 is configured to support the probe 204. In a variation, the console 218 rests on a table, a desk, a stationary cart, etc. with the monitor 210 either part of the console (e.g., similar to a laptop) or a separate device in electrical communication therewith.
The touch sensitive region 222 includes a worksheet region 302 (e.g., the display workspace 232 in
As briefly discussed above, the worksheet region 302 is configured to display an editable digital worksheet. Editable means the worksheet region 302 can display a form with pre-determined regions which can be selected to toggle between pre-determined options, e.g., a check box that can be toggled between “checked” and “unchecked” states. Editable may also mean a pre-determined region can be activated to allow alpha-numeric and/or graphic indicia entry via a soft and/or physical keyboard, a gesture on the touch screen (e.g., via one or more fingers, a stylus, a digital pen, etc.), voice recognition, etc. The term editable is not limited to these example definitions.
The controls region 304, as briefly discussed above, includes one or more soft controls. The displayed and/or activated soft controls may be grouped, e.g., soft keys that control the imaging parameters may be grouped together. Such controls may become visible and/or activated depending on the point in examination (e.g., protocol and/or parameter selection, scanning, taking measurements, etc.). The control groupings can be default, facility specific, user specific, scanning mode specific, etc.
With the touch sensitive region 222 of
This also allows for reduction in the aggregate time of scanning and reporting by the clinician, relative to a configuration in which the sonographer would either halt the imaging or end the exam in order to complete or partially fill in the worksheet or report. For example, the overall procedure time may be decreased by as much as several minutes. As such, the system 102 is well-suited for examinations that require quick diagnosis and reporting, such as those for emergency medicine ultrasound. Moreover, this reduces the amount of time a patient has to wait for a scan.
In one embodiment, the user can scroll the worksheet frame by swiping (e.g., up, down, right, left, diagonal, irregular, etc.) at least one finger, stylus, etc. on the touch screen. Such scrolling action will result in the information that is not initially visible on the screen to become visible. The scrolling may be performed the same way as it may be performed on conventional touch screens such as the ones in most smart phones. In another embodiment, the scrolling action within the worksheet frame can be performed by pressing hard keys, soft keys or soft controls on the touch panel.
In the illustrated example, the visible sub-portion includes checkboxes 1205 next to pre-established options 1206 (e.g., option 1, option 2, option 3, option 4), which are categorized by item 1208 (e.g., item 1, item 2, etc.). In one example, the items 1208 may provide an organ list, an exam list, an image list, etc. and checked options indicate the organ, exam, list, etc. for the examination. Other options may be associated with yes or no conclusions, positive, negative or inconclusive conclusions, etc. Alternative to a list, the options may be in drop down and/or other menus, etc.
It is to be appreciated that the above and/or other changes to the worksheet region 302 can be performed without interrupting or halting the scanning procedure.
In the illustrated example, the pre-determined anatomical representation 1302 illustrates left and right breasts, and the graphical indicia 1304 indicates a position of a suspected tumor. In other example, the graphical indicia 1304 may indicate of tissue (e.g., a cyst, scare tissue, previous biopsy site, etc.). In yet another example, the pre-determined anatomical representation 1302 may indicate other tissue, e.g., prostate, liver, kidneys, gallbladder, pancreas, thyroid, heart, muscles, reproductive organs, abdominal organs, etc. A database of anatomical drawings of body organs can be stored in various worksheets or on the ultrasound system 102.
In one embodiment, the clinician can mark the representation 1302 while the scanning is performed (i.e., concurrent use of the regions 302 and 304). The clinician can thus touch within the region 302 to place the graphical indicia 1304 on the representation 1302 and/or move already-placed graphical indicia 1304 to a different location. In another embodiment, the clinician can pause or end the examination and consequently edit the representation 1302 within the worksheet. The edited representation 1302 can be stored as part of the worksheet or report, otherwise stored, discarded, modified, printed, etc.
