Claim 4:
5. An ultrasonic flow spectral Doppler imaging system, comprising:
a transmitting circuit that is configured to transmit an ultrasonic beam to an examination object;
a receiving circuit that is configured to receive echoes of the ultrasonic beam to obtain an ultrasonic echo signal:
an image processor that is configured to obtain an ultrasonic image of a region of interest in the examination object according to the ultrasonic echo signal, determine a first sampling position in the region of interest and obtain a first Doppler spectrum corresponding to the first sampling position according to the ultrasonic echo signal, determine a second sampling position in the region of interest and obtain a second Doppler spectrum corresponding to the second sampling position according to the ultrasonic echo signal; and
a display having first, second, and third areas, wherein the ultrasonic image is displayed with markers of the first and second sampling position in the first area, and the first Doppler spectrum and second Doppler spectrum are simultaneously displayed in the 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.
