Abstract: An ultrasound system includes: an ultrasound device having a two-dimensional array of ultrasound transducers; and a smartphone or tablet in operative communication with the ultrasound device. The ultrasound system is configured to: collect multiple sets of ultrasound data from multiple regions within the subject; detect fetal heartbeat signals and uterine contraction signals; monitor a fetal heartbeat signal among the fetal heartbeat signals by automatically steering an ultrasound beam to a first region among the multiple regions within the subject to collect first further ultrasound data from the first region based on a quality of the fetal heartbeat signal; and monitor a uterine contraction signal among the uterine contraction signals by automatically steering the ultrasound beam to a second region among the multiple regions within the subject to collect second further ultrasound data from the second region based on a quality of the uterine contraction signal.

Abstract: Aspects of the technology described herein relate to built-in self-testing (BIST) of circuitry (e.g., a pulser or receive circuitry) and/or transducers in an ultrasound device. A BIST circuit may include a transconductance amplifier coupled between a pulser and receive circuitry, a capacitor network coupled between a pulser and receive circuitry, and/or a current source couplable to the input terminal of receive circuitry to which a transducer is also couplable. The collapse voltages of transducers may be characterized using BIST circuitry, and a bias voltage may be applied to the membranes of the transducers based at least in part on their collapse voltages. The capacitances of transducers may also be measured using BIST circuitry and a notification may be generated based on the sets of measurements.

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: A method includes: obtaining an ultrasound image of an anatomical area from an ultrasound imaging device; inputting the ultrasound image into a first stage of a convolutional neural network, the first stage configured to determine key-point locations of the anatomical area; generating, for each of the key-point locations, a cropped region of the ultrasound image; inputting each of the cropped regions into a second stage of the convolutional neural network, the second stage configured to locate an anatomical landmark of the anatomical area; and outputting a location of the anatomical landmark.

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: Aspects of the technology described herein related to controlling, using control circuitry, modulation circuitry to modulate and delay first ultrasound data generated by first ultrasound transducers positioned at a first azimuthal position of an ultrasound transducer array of an ultrasound device and second ultrasound data generated by second ultrasound transducers positioned at a second azimuthal position of the ultrasound transducer array of the ultrasound device, such that the first ultrasound data is delayed by a first delay amount and the second ultrasound data is delayed by a second delay amount that is different from the first delay amount. The first and second ultrasound data received from the modulation circuitry may be filtered and summed. The ultrasound transducer array, the control circuitry, the modulation circuitry, the filtering circuitry, and the summing circuitry may be integrated onto a semiconductor chip or one or more semiconductor chips packaged together.

Abstract: A method of forming an ultrasonic transducer device involves depositing a first layer on a substrate, depositing a second layer on the first layer, patterning the second layer at a region corresponding to a location of a transducer cavity, depositing a third layer that refills regions created by patterning the second layer, planarizing the third layer to a top surface of the second layer, removing the second layer, conformally depositing a fourth layer over the first layer and the third layer, defining the transducer cavity in a support layer formed over the fourth layer; and bonding a membrane to the support layer.
