PHYSICAL MODELS Development of mathematical models of impedance characteristics of biological soft tissues, having, obviously, an independent scientific interest, is the most important stage of development of the method to reconstruct mechanical parameters of multi-layered tissues and the method of continuous monitoring of tissues viscoelastic parameters with high time resolving power. A base of the acoustic theory of tissues mechanical impedance, explaining its relationship, both with parameters of indentor, and with parameters of tissues, was laid in 1951 by Oestreicher. More strict acoustic models of impedance characteristics of biological tissues were offered relatively recently. In particular, so-called "models with the pressure source of vibrations", based on the approach, taken when solving the Lamb's problem, were offered in IAP RAS.
