Abstract
A method for measuring a mean visco-elasticity value for a soft material using a single probe carrying at least one transducer includes inducing, in a constraint zone, at least one burst of mechanical vibrations in order to generate internal shear waves in the tissue propagating from the constraint zone into the tissue, measuring, with the transducer, transient tissue displacements in at least one first measurement zone in the tissue, the first measurement zone being located away from the constraint zone, and estimating a mean visco-elasticity of the region of the tissue situated between the constraint zone and the first measurement zone from the measured transient tissue displacements of the tissue in the first measurement zone.
