摘要：An ultrasonic diagnostic imaging system for shear wave measurement transmitspush pulses into tissue for the generation of shear waves. Characteristics of the shearwaves such as their velocity of passage through the tissue are measured to assessproperties such as tissue stiffness. The measurements are compensated for effects ofbackground motion by sampling echo signals from the tissue at different times andcomparing the samples to detect the presence of relative motion between theultrasound probe and the region of interest where shear waves are detected. Sensedbackground motion is used to adjust measured shear wave characteristics.
