Claim 0:
1. An ultrasonic imaging apparatus, comprising:
a probe;
a transmitting circuit configured to excite the probe to transmit ultrasonic waves to a region of interest containing a vessel;
a receiving circuit configured to receive echo signals generated after the transmitting of the ultrasonic waves; and
a processor configured to:
obtain an ultrasonic image of the region of interest according to the echo signals;
obtain particle jet velocities at multiple points in the vessel according to the echo signals, wherein the particle jet velocity comprises a velocity magnitude and a velocity direction;
determine a vascular wall in the ultrasonic image, and obtain a measurement position on the vascular wall;
calculate a vascular wall shear index at the measurement position according to the particle jet velocities at a plurality of points near the measurement position; and
display the ultrasonic image and the vascular wall shear index on a display device.
