Eine neue Methode zur nicht-invasiven Messung von elastischen Eigenschaften lebenden Gewebes

摘要

A new approach is proposed based upon the theory that the velocity of sound waves propagating in a material depends on the elasticity of the sample. In this study an investigation is conducted to find out whether the respective engineering laws apply to the mechanical and acoustic properties of biological living tissue. A model describing the mechanical behaviour of biological tissue is developed taking non-linear mechanical tissue properties into account. A method is proposed to determine the sound velocity non-invasively, and a simulation of the propagation of ultrasonic waves in stratified materials was performed.
