Patent ID: 8758249

Claim:
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) before filtering Doppler signals extracted from the echo signals, performing Doppler estimation directly on the Doppler signals extracted from the echo signals, to acquire Doppler parameters of stationary tissue and nonstationary tissue or blood flow within the target area, wherein the Doppler parameters comprise at least velocity and power; and c) filtering, based on the acquired velocity of the Doppler parameters of stationary tissue and nonstationary tissue or blood flow, the acquired power of the Doppler parameters of stationary tissue and nonstationary tissue or blood flow to obtain the power related to the nonstationary tissue within the target area, so as to display the tissue motion.
