Claim 19:
20. 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 and a measurement position in the ultrasonic image;
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 of the vascular wall;
generating an index mark, wherein an attribute of the index mark corresponds to a calculated value of the vascular wall shear index; and
displaying the index mark corresponding to the measurement position at the measurement position on the vascular wall.
