Claim 26:
27. The ultrasound imaging system of claim 25, wherein:
the transmitting circuit excites the probe to transmit the plane ultrasound beams along an ultrasound propagation direction;
the receiving circuit and the beam-forming unit receive the echoes of the plane ultrasound beams to obtain a group of plane ultrasound echo signals; and
the data processing unit obtains at least two frames of image data according to the group of plane ultrasound echo signals, selects a tracking region in a first frame of image data and searches a tracking result region in a second frame of image data which corresponds to the tracking region, obtains the flow velocity vector information of the randomly-selected target points according to locations of the tracking region and the tracking result region and a time interval between the first frame and the second frame of image data, and obtains the Doppler flow velocity information according to the group of plane ultrasound echo signals.
