Abstract: An ultrasonic transducer array includes a plurality of functional micromachined ultrasonic transducers (MUTs), each having a cavity of a first diameter. One or more groups of non-functional MUTs are disposed about a perimeter of the functional MUTs, the one or more groups of non-functional MUTs having a cavity of a second diameter that is smaller than the first diameter.

Abstract: Aspects of the technology described herein relate to enhancing ultrasound data. Some embodiments include receiving ultrasound data and automatically determining, with a processing device, that the ultrasound data depicts an anatomical view or one of a set of anatomical views. Based on automatically determining that the ultrasound data depicts the anatomical view or one of the set of anatomical views, an option is enabled to perform ultrasound data enhancement specific to the anatomical view or the set of anatomical views. Based on receiving the selection of the option, the ultrasound data, a portion thereof, and/or subsequently-collected ultrasound data is enhanced using the ultrasound data enhancement specific to the anatomical view or the set of anatomical views.

Abstract: A graphical user interface displayed by a processing device in operative communication with an ultrasound device may include a preset filter option that provides an easy way to switch between different presets which belong to a preset family. The user uses the preset filter feature to cycle through the different presets in the family while remaining on the same screen that is showing ultrasound images collected in real time. The imaging depth remains the same while the user is using the preset filter feature to select the preset within a family. Other settings such as time-gain compensation may not remain the same when cycling between presets. The preset filter feature allows a user to continuously view and assess the ultrasound images being collected in real time while cycling through the presets in the family.

Abstract: Disclosed herein are systems and methods for automatically updating scan patterns used during ultrasound imaging. A handheld ultrasound system may include an ultrasound device with a two-dimensional array of ultrasound transducers, and a smartphone or tablet that configures the ultrasound device to obtain a first ultrasound image frame using a scan pattern defining an acoustic beam. The system then updates the scan pattern to optimize a view of the desired anatomy. When the system is operating in cardiac imaging mode, the scan pattern may be updated by adjusting the azimuthal tilt and/or the elevational tilt of the acoustic beam. When the system is operating in lung imaging mode, the scan pattern may be updated by adjusting the elevational tilt and/or the translation of the aperture of the array of ultrasound transducers. The system then configures the ultrasound device to obtain a second ultrasound image frame using the updated scan pattern.

Abstract: Aspects of the present application provide methods and apparatus for directing operation of an ultrasound device. Some aspects provide various instructions to a user of the ultrasound device, automatically detect when the user has completed a step based on ultrasound images collected by the ultrasound device, and automatically transitioning to providing an instruction for a following step. The instructions may relate to positioning of the ultrasound device and application of an ultrasound coupling medium, in some embodiments.

Abstract: Ultrasound devices are disclosed. The ultrasound devices have an elevational dimension. Different percentages of the aperture of the ultrasound device corresponding to different percentages of the elevational dimension are utilized in different applications. The resolution of imagine may be adjusted in connection with usage of different percentages of the aperture.

Abstract: A system for coherence imaging may receive ultrasound signals each having a respective delay associated with a respective ultrasonic transducer element in an ultrasonic transducer array. The system may obtain an approximation of the auto-correlation of ultrasound signals without any auto-correlation calculation, and determine the output image based on the approximation. In approximating the auto-correlation, the system may group the ultrasound signals into multiple portions, each corresponding to a respective sub-aperture of a plurality of sub-apertures of the ultrasonic transducer array. The system may determine a coherent sum of signals for each sub-aperture, perform a square operation or magnitude square operation over the coherent sum to obtain resulting data, normalize the resulting data, and sum the resulting data for all of the sub-apertures to generate the output image. A sub-aperture in the plurality of sub-apertures may overlap with another sub-aperture.

Abstract: Ultrasound devices are described. The ultrasound devices may be flexibly configured to output a certain number of multilines per channel of ultrasound data and to process certain channels of ultrasound data per processing cycle. The ultrasound device may then be configured to either output more multilines per channel and process fewer channels per processing cycle, or output fewer multilines per channel and process more channels per processing cycle. In other words, the circuitry may be configured to change to a configuration with increased resolution and increased processing time or to a configuration with decreased resolution and decreased processing time.

Abstract: Technology for guiding a user to collect clinically usable ultrasound images is described. In some embodiments, an ultrasound device may automatically change the elevational steering angle of its ultrasound beam (e.g., using beamforming) in order to collect ultrasound data from different imaging planes within the subject. A processing device in operative communication with the ultrasound device may select one of the collected ultrasound images based on its quality (e.g., select the ultrasound image having the highest quality), and then continue to collect ultrasound images using the elevational steering angle at which the selected ultrasound image was collected.
