Method and device for ultrasonic imaging by synthetic focusing

A synthetic focusing ultrasound imaging apparatus, including:

• an activation transmission module for activating a plurality of elements of an ultrasound probe to transmit plane waves multiple times, wherein transmit apodizations are formed in each event that the plurality of transmit plane waves correspond to a row in a measurement matrix, wherein elements of the measurement matrix obey a random distribution;
• an activation acquisition module for activating all elements of the ultrasound probe to receive echo signals to obtain channel data after each plane wave transmission;
• a data recovery module for recovering a synthetic focusing channel dataset by utilizing a compressed sensing reconstruction algorithm according to a channel dataset and the measurement matrix, wherein the channel dataset is a set of the channel data;
• and
• an image reconstruction module for beamforming the synthetic focusing channel dataset to generate an ultrasound image.
