Abstract
Disclosed are an ultrasonic imaging method, an ultrasonic imaging system and a computer storage medium. The method includes: transmitting ultrasonic waves to a region of interest, including transmitting multiple pulses to the same target position (S110); receiving ultrasonic echoes to obtain an ultrasonic echo signal (S120); performing beam synthesis to obtain a beam-synthesized signal for each transmission (S130); performing autocorrelation calculation on the beam-synthesized signal for each transmission to obtain an autocorrelation function characterizing the blood flow signal for each transmission (S140); synthesizing the autocorrelation functions obtained after multiple transmissions to obtain a synthesized autocorrelation function (S150); and obtaining a color blood flow image based on the synthesized autocorrelation function (S160).
