US 8,147,410 B2 · Method and apparatus for ultrasound imaging and elasticity measurement

Abstract

A method for performing ultrasound imaging and elasticity measurement, the method includes scanning an object to obtain a B-mode ultrasound image, selecting an A-mode signal from the B-mode ultrasound image, transmitting a high frame rate ultrasound signal, by a selected group of ultrasound transducers, at the selected A-mode signal location, forming a transient M-mode image based on the high frame rate ultrasound signal, enhancing propagation trace of shear wave based on the transient M-mode image, calculating elasticity of the object based on the propagation trace and displaying result, and displaying, simultaneously, the B-mode ultrasound image and the transient M-mode measurement result.
