Abstract
Provided are a method and device for ultrasonic imaging by synthetic focusing. The method comprises: exciting a plurality of matrix elements of an ultrasonic probe to transmit plane waves many times, wherein transmitting apodizations at the time of every transmission of the plane waves by the plurality of matrix elements correspond to the respective lines in a measurement matrix in which elements are randomly distributed; after every transmission of the plane waves, exciting all the matrix elements of the ultrasonic probe to receive echo signals, in order to obtain channel data; recovering a synthetic focusing channel data set by use of a compressed sensing reconstruction algorithm according to a channel data set and the measurement matrix; and subjecting the synthetic focusing channel data set to beamforming so as to generate an ultrasonic image.
