Abstract
The invention relates to a method for measuring a mean visco-elasticity value for a soft material. The method uses a single probe carrying at least one transducer and includes the steps of: (a) 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, (b1) measuring, with the transducer, the transient tissue displacements in at least one first measurement zone in the tissue, and wherein the first measurement zone is located away from the constraint zone, and (c) 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.
