METHOD AND APPARATUS FOR MEASURING A PHYSICAL PARAMETER IN MAMMAL SOFT TISSUES BY PROPAGATING SHEAR WAVES.

摘要

Method for measuring a physical parameter in soft tissues of a mammal, in which a mechanical shear wave is propagated through the soft tissues and observation of the propagation leads to determine values of a shear wave propagation parameter. The physical parameter computed on the basis of these values is either a parameter of non-linearity of elasticity of a soft-tissue (blood vessel) being subject to blood pressure on the temperature of the soft tissue.
