Ultrasonic method for quantifying the nonlinear elasticity by shear waves of a medium, and device for carrying out this method An ultrasonic method for quantifying the nonlinear shear wave elasticity of a medium, the method comprising the following steps: A1. - the collection of a temporal succession of elasticity data by medium shear waves, A2. - an application of a successively changing deformation to the medium according to a predetermined sequence of deformations during the collection of the shear waves, A3. - the observation of the evolution of real deformation, and B. - the quantification of the nonlinear elasticity of the medium as a function of the temporal succession of data and the evolution of deformation.
