Abstract
A method for ultrasound imaging is provided. The method includes at least a transmission step, a coherence enhancing step, and a beamforming step. In the transmission step, a plurality of ultrasonic waves are transmitted into an imaged region and a set of raw data is acquired by an array of transducers in response to each ultrasonic wave. The ultrasonic waves have different spatial frequency content. In the coherence enhancing step, for each of a plurality of virtual transmit focal zones in the imaged region, at least one set of coherent data is synthesized from the sets of raw data. In the beamforming step, for each of a plurality of locations included in each of the virtual transmit focal zones, an image pixel is computed by beamforming, using the set of coherent data.
