Abstract
The wave number and phase velocity (shear wave speed) of ultrasound energy within an organ of interest are calculated using a herein-disclosed phase gradient calculation method. This calculation method is less sensitive to imperfections in the reverberant field distribution and requires a smaller support window, relative to earlier calculation methods based on autocorrelation. Applications are shown in simulations, phantoms, and in vivo liver.
