1. An ultrasonic imaging method, comprising:
transmitting ultrasonic waves to a region of interest of a target object, said transmitting ultrasonic waves comprising transmitting pulses to a same target position for multiple times;
receiving ultrasonic echoes of the ultrasonic waves to obtain ultrasonic echo signals;
performing a beam synthesis on the ultrasonic echo signals obtained by each transmission to obtain a beam synthesized signal of each transmission;
performing an autocorrelation calculation on the beam synthesized signal of each transmission to obtain an autocorrelation function of each transmission representing a blood flow signal;
performing a synthesis on the autocorrelation functions of the multiple transmissions to obtain a synthetic autocorrelation function; and
obtaining a color blood flow image of the region of interest according to the synthetic autocorrelation function.
