[Methods of tissue characterization with ultrasonic spectroscopy, analysis of the results obtained, prospects for clinical application in a short time].
So far, to account for ultrasonic attenuation in soft tissues molecular scale relaxation theory is retained. In addition to these mechanisms, the authors have obtained experimental evidence proving the role also plaid by cellular scale resonance mechanisms. Moreover, in addition to incoherent diffusion, it has been found that some tissues exhibit some coherent diffusion. All these experimental findings allows us to establish the feasability of non invasive ultrasonic biopsies.
