    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: 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: 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.
