Abstract

Energy is considered to be absorbed by hydrolysis in the constituents of tissue, by low frequency relaxation processes, and by the relaxation process of motions of side chains alone at high frequencies. The authors describe a study on tissue relaxation processes with application to fatty hen liver tissue characterization by ultrasonic absorption spectrum analysis using the fundamental component and the second harmonic component
