    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: 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: 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.
