  • Publication number: 20220265249
    Abstract: The present embodiments relate generally to methods for providing viewing access to an ultrasound image feed generated at an ultrasound imaging machine. A multi-use display device may form a first link-layer connection with the ultrasound image machine for transmitting commands that control imaging parameters of the ultrasound image feed. The multi-use display device may then: determine link-layer connection parameters that allow the ultrasound imaging machine to form a second link-layer connection with a receiving device (the receiving device having no link-layer connection with the ultrasound imaging machine), and provide the connection parameters to the receiving device. The ultrasound imaging machine forms a second link-layer connection with the receiving device, based the connection parameters. The second link-layer connection is then used for receiving, at the receiving device, the ultrasound image feed controlled by the multi-use display device.

  • Publication number: 20220047241
    Abstract: A plurality of ultrasound frames of a fetus are acquired using an ultrasound scanner, which may be oriented arbitrarily with respect to the fetus during the acquisition. The ultrasound frames are processed against an artificial intelligence model to predict a different cut line on each of the ultrasound frames. Each cut line is predicted to be exterior to an image of the fetus appearing on the ultrasound frame. The different cut lines on the plurality of ultrasound frames are then used to identify ultrasound data in the image frames to generate a 3D representation of the fetus.

  • Publication number: 20210383503
    Abstract: Ultrasound images are adjusted according to the size of the display area available to display them, so that image detail is displayed with a large enough physical size to discern comfortably. A translation ratio is determined for translating the physical distance traversed by the ultrasound signals of an ultrasound images to a corresponding physical distance on a screen of the display device. If the ratio is not below a threshold, the image is displayed in full. If the ratio is below the threshold, the image is cropped, optionally scaled, and displayed in the available area. Scaling and cropping may be based on window size and threshold window size. The parameters of the ultrasound scan may be controlled based on the scaling, cropping, or available screen size. User interface features may be displayed on the screen depending on how much area is available when the image is displayed.

  • Publication number: 20210186463
    Abstract: Ultrasound scanners that are initialized and placed to the side in a sterile bag for use in a sterile environment may suffer overheating and cut out early, because the bag represents a poor cooling environment. The rate of increase in temperature of a scanner is monitored and a determination is made as to whether the scanner is in a regular environment or a poor cooling environment. If the scanner is in a poor cooling environment, the scanner is switched from a regular state of operation to a poor cooling state of operation. In the poor cooling state of operation, the scanner settings consume less power and generate less heat on the whole than the regular scanner settings. The scanner reverts to higher power settings as and when needed to perform the desired scan. The user interface on an associated display device also changes in response to the scanner entering the poor cooling state of operation.

  • Publication number: 20210022716
    Abstract: An ultrasound scanner in a spectral Doppler mode, in which a corresponding two-dimensional (2D) ultrasound imaging mode (e.g., B-mode) image is frozen, is switched temporarily to the 2D-mode in response to a continuous contact on a touchscreen. During the continuous contact, the spectral Doppler mode is interrupted, the 2D-mode image becomes live, and the gate for the spectral Doppler mode may be adjusted by a movement of the continuous contact on the touchscreen. Upon termination of the continuous contact, the system reverts back to the spectral Doppler mode, which now operates within the adjusted gate, and the 2D-mode image is frozen. A brief contact may be used to check the position of the gate against a live 2D-mode image without adjusting it.

  • Publication number: 20210015464
    Abstract: The present embodiments relate generally to ultrasound imaging systems and methods that provide a user interface on the touchscreen display. The user interface includes an ultrasound image feed and a single control for modifying imaging depth of the ultrasound image feed. When input via the single control is received to modify the imaging depth, the system: adjusts frequency of ultrasound signals being used to acquire the ultrasound image feed; adjusts a beamformer parameter of the ultrasound signals being used to acquire the ultrasound image feed; receives first image data of the ultrasound image feed based on the adjusted frequency and the adjusted beamformer parameter; based on the first image data, adjusts Time Gain Compensation (TGC) of the ultrasound image feed; and receives second image data of the ultrasound image feed based on the adjusted frequency, beamformer parameter and TGC. Display of the second image data on the touchscreen display is then optimized without receipt of additional user input.

  • Publication number: 20200352546
    Abstract: Mobile ultrasound scanners require a screen that acts as a display and user interface, yet there is often no convenient location for the screen. A mobile ultrasound scanner is therefore set up as a user interface to control a screen that is already in-situ. The ultrasound scanner wirelessly communicates with a separate interface module that controls a previously paired screen. When the scanner is in range of the interface module, the screen switches on. The interface module operates in an ultrasound scanning mode and optionally a user navigation mode, to which the screen display corresponds. The scanner operator can perform an ultrasound scan and provide user inputs without having to touch the screen. The scanner may have at least one physical button for operator input and/or a multi-axis accelerometer/gyroscope that detects gestures made using the scanner.
