Role Played by Cellular Cohersion and Organization in the Interaction of Ultrasound with Soft Tissues
The absorption of soft tissues has so far been explained by relaxation phenomena on the macromolecular scale. That these phenomena are involved cannot be denied since this is proved by many experiments carried out on pure solutions of macromolecules. But these mechanisms do not justify the significant differences in attenuation measured in different tissues or the different pathological states of the same tissue.
