1. An ultrasound imaging method, comprising:
transmitting ultrasound waves to a target tissue of a subject at least three different transmission angles, wherein the ultrasound waves comprise first ultrasound waves at least two first transmission angles having different transmitting frequencies, and second ultrasound waves at least two second transmission angles having a same transmitting frequency;
receiving an echo of each of the ultrasound waves at each transmission angle to obtain an ultrasound echo signal corresponding to each transmission angle;
for the ultrasound echo signal corresponding to each transmission angle, performing beamforming at least two different receiving angles to obtain beamformed data corresponding to the different receiving angles;
based on each transmission angle, receiving angles, and a transmitting frequency corresponding to the beamformed data, performing at least one coherent compounding and at least one non-coherent compounding on the beamformed data to obtain compounded data, wherein each coherent compounding comprises performing coherent compounding on beamformed data corresponding to a same receiving angle, the same transmitting frequency, and different transmission angles to obtain a set of coherently compounded data corresponding to the same receiving angle and the same transmitting frequency, and each non-coherent compounding comprises performing non-coherent compounding on at least one set of coherently compounded data and beamformed data not subjected to the coherent compounding; and
generating an ultrasound image based on the compounded data.
