Claim 18:
19. A method for detecting a vascular wall shear index using ultrasonic waves, comprising:
transmitting ultrasonic waves to a region of interest containing a vessel;
receiving echoes to obtain echo signals;
obtaining an ultrasonic image according to the echo signals;
obtaining 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;
determining a vascular wall in the ultrasonic image;
obtaining a measurement position on the vascular wall;
calculating the vascular wall shear index at the measurement position according to the particle jet velocities at a plurality of points near the measurement position; and
displaying the ultrasonic image and the vascular wall shear index.
