Abstract
Systems, devices, and methods for ultrasonic imaging by sparse sampling are provided. In one embodiment, an ultrasound imaging system comprises an array of ultrasound transducer elements, electronic circuitry in communication with the array of ultrasound transducer elements and configured to select a first receive aperture of the array comprising a plurality of contiguous ultrasound transducer elements and at least one non-contiguous ultrasound transducer element, and a beamformer in communication with the electronic circuitry. Each ultrasound transducer element of the first receive aperture is configured to receive reflected ultrasound echoes and generate an electrical signal representative of imaging data. The beamformer is configured to receive the electrical signals generated by the first receive aperture and apply different weight to the electrical signals generated by the contiguous ultrasound transducer elements and the electrical signal generated by the at least one non-contiguous ultrasound transducer element.
