摘要：
Inspired by seismic-noise correlation and time reversal, a shear-wave tomography of soft tissues using an ultra-fast ultrasonic scanner is presented here. Free from the need for controlled shear-wave sources, this passive elastography is based on Green's function retrieval and takes advantage of the permanent physiological noise of the human body.
