Abstract: Aspects of the technology described herein relate to techniques for guiding an operator to use an ultrasound device. Thereby, operators with little or no experience operating ultrasound devices may capture medically relevant ultrasound images and/or interpret the contents of the obtained ultrasound images. For example, some of the techniques disclosed herein may be used to identify a particular anatomical view of a subject to image with an ultrasound device, guide an operator of the ultrasound device to capture an ultrasound image of the subject that contains the particular anatomical view, and/or analyze the captured ultrasound image to identify medical information about the subject.

Abstract: The systems and methods for capturing images using ultrasound and in particular, systems that provide an ultrasound probe having a two-dimensional (2D) array of ultrasound transducers elements. The systems leverage the 2D array of transducer elements to achieve beam steering over the generated ultrasound signals. The system applies beam steering to generate multiple ultrasound signals which are, in sequence, transmitted across the elevational dimension of the 2D transducer array and at different angles of orientation. Each transmission in the sequence can be treated as a slice of a final image (whether still or video) that can be presented on a display. The final image is generated by image processing the multiple different slices of images to join the images slices together into a composite image. The joined images may be presented on a display to the user. Optionally, the joined images may be presented as a video of images made by sweeping the ultrasound beam over an anatomical target.

Abstract: A method includes: determining, by a host device, a predetermined path including a first tilt from which a target anatomical view is available and a second tilt from which the target anatomical view is not available, where the predetermined path has a pivot of fewer than 180 degrees about an anatomical area; instructing, by the host device, an operator to pivot an ultrasound device along the predetermined path by displaying a display on the host device; receiving a first ultrasound image depicting the target anatomical view and a second ultrasound image not depicting the target anatomical view based on ultrasound data collected by the ultrasound device while pivoting along the predetermined path; and identifying that the first ultrasound image depicts the target anatomical view. The predetermined path is determined prior to collecting the first ultrasound image and the second ultrasound image.

Abstract: An ultrasound system includes an ultrasound probe and a mobile device in operative communication with each other. The ultrasound probe includes three buttons-an up button, a center button, and a down button-disposed on the external housing. The mobile device may be configured to receive an indication from the ultrasound probe of a double press of the center button when the mobile device is displaying a scan screen. Based on the double press of the center button, the mobile device may be configured to display a button function configuration menu on the scan screen, receive a selection from the button function configuration menu of a button function configuration, receive an indication of a single press of the up button or the down button, and perform an action in accordance with the single press of the up button or the down button and the button function configuration.

Abstract: Micromachined ultrasonic transducers having pressure ports are described. The micromachined ultrasonic transducers may comprise flexible membranes configured to vibrate over a cavity. The cavity may be sealed, in some instances by the membrane itself. A pressure port may provide access to the cavity, and thus control of the cavity pressure. In some embodiments, an ultrasound device including an array of micromachined ultrasonic transducers is provided, with pressure ports for at least some of the ultrasonic transducers. The pressure ports may be used to control pressure across the array.

Abstract: Beamforming circuitry for an ultrasound device is disclosed, that may directly calculate the position in receive line space for an incoming ultrasound data sample given the time of flight (ToF) of that ultrasound data sample. In some embodiments, this may be done without initially buffering the ultrasound data sample received from the particular receive datapath multiplexed to the beamforming circuitry. The beamforming circuitry may then associate the ultrasound data sample with that position in receive line space, and in particular, with a memory address corresponding to that location. Thus, when the beamforming circuitry multiplexes between different receive datapaths, it may not need to buffer ultrasound data samples from different receive datapaths prior to saving the data to memory.
