Claim 0:
1. An ultrasonic flow spectral Doppler imaging method, comprising:
transmitting an ultrasonic beam to an examination object;
receiving echoes of the ultrasonic beam to obtain an ultrasonic echo signal:
obtaining an ultrasonic image of a region of interest in the examination object according to the ultrasonic echo signal;
determining a first sampling position in the region of interest and obtaining a first Doppler spectrum corresponding to the first sampling position according to the ultrasonic echo signal;
determining a second sampling position in the region of interest and obtaining a second Doppler spectrum corresponding to the second sampling position according to the ultrasonic echo signal:
displaying, in a first area of a display, the ultrasonic image with markers of the first and second sampling positions; and
simultaneously displaying the first Doppler spectrum and the second Doppler spectrum in second and third areas of the display, respectively, wherein first Doppler spectrum and second Doppler spectrum are synchronously displayed along a same time axis, the first Doppler spectrum is assigned with a first color identifier, the second Doppler spectrum is assigned with a second color identifier, a color of the first color identifier different from a color of the second color identifier, the marker of the first sampling position has the same color as that of the first color identifier, and the marker of the second sampling position has the same color as that of the second color identifier.
