Abstract
A system and method for determining tissue changes. Shear waves are transmitted across the tissue in response to an ultrasonic signal input exterior to the tissue surface. Adaptive beam forming signal processing is applied to signal returns and arrivals to remove distortions by targeting velocity contrasts. Shear-wave dispersion, such as due to viscosity and mass changes in the tissue, are then estimated and compared to reference data to determine tissue health.
