Abstract: Methods and systems for ultrasound imaging and beamforming with a matrix array of transducer elements are provided. Receive signals of each transducer array element are amplified. The amplified receive signal of each transducer array element is digitized. A delay and weight are applied on the amplified and digitized receive signals. The amplified, digitized, delayed, and weighted receive signals are summed across all transducer elements of the matrix array to form a dynamically focused receive beam. An application specific integrated circuit (ASIC) that is integrated with the matrix array of transducer elements performs such steps.

Abstract: Described herein are methods and systems for testing transducers and associated integrated circuits. In some cases, a method or system described herein can comprise modulating a bias voltage using a test signal in order to produce a modulated bias voltage signal useful in testing a plurality of transducers of a transducer array in parallel.
