Abstract:
1. A method of ultrasound imaging comprising: splitting an array of ultrasound elements into a set of sub-apertures; sequentially transmitting a plurality of beamformed pulses along a focused line of sight, such that the beamformed pulses are transmitted from different sub-apertures; after each transmit event, receiving echoes with the array of ultrasound elements, thereby obtaining a set of signals associated with each transmit event; applying receive beamforming time delays to each set of signals and calculating phase coherence weighting factors for each set of signals; employing the phase coherence weighting factors to generate a weighted beamformed signal for each set of signals; and adding the weighted beamformed signals to generate a line of an ultrasound image.
