[Reflection of ultrasound from intertissue boundaries].
A bioacoustic model of the intermediate layer in the form of plane-parallel passive elastic medium is examined. Theoretically the structural-functional factors influencing ultrasonic reflection from intermediate boundaries are found. The results of modelling were tested in experiment with operative material of human soft tissues. Recorded variations of the reflection coefficient of ultrasound may be explained by changes in the common tissues in pathological processes. A suggestion about probable informative role of intermediate layers of the organism was made.
