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.
