Method and apparatus for tissue doppler imaging
First Claim
1. A method for Tissue Doppler Imaging, comprising the steps of:
- a) transmitting ultrasound signals to a target area including the tissue to be imaged, and receiving the echo signals returned from the target area;
b) performing Doppler estimation on Doppler signals extracted from the echo signals, to acquire Doppler parameters of stationary tissue or nonstationary tissue or blood flow within the target area, wherein the Doppler parameters comprise at least velocity and power;
c) processing the acquired power of the Doppler parameters to obtain the power related to the nonstationary tissue within the target area, so as to display the tissue motion.
