Abstract
An ultrasound system and method for calculation and display of tissue deformation parameters, such as tissue Doppler and strain rate imaging, are disclosed. An ultrasound acquisition technique that allows a high frame rate in tissue velocity imaging or strain rate imaging is employed. With this acquisition technique the same ultrasound pulses are used for the tissue image and the Doppler based image. The number of beams used in Doppler subframes are increased to allow tissue visualization based only on Doppler subframes. A sliding window technique is used for processing.
