Determination of the acoustic nonlinearity parameter in biological media using FAIS and ITD methods.

Abstract

Two methods for determination of the acoustic nonlinearity parameter B/A in biological media are presented. One is the finite amplitude insert-substitution method (FAIS), considering the influence of both the sound attenuation of samples and the diffraction of the transducer on the experimental measurement. The other is the improved thermodynamic method… (More)
