| 发明名称 | Method and apparatus for tissue doppler imaging | ||
| 摘要 | A method for Tissue Doppler Imaging is provided. The method for Tissue, Doppler Imaging comprises 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. | ||

| 主权项 | 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) 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. | ||
