Abstract

A method for constructing images of the acoustic nonlinearity parameter in the transmission mode is presented. It is based on measuring the loss in the transmitted signal due to the nonlinear mix of two frequencies of propagating sound waves. The gray scale images of a breast phantom thus obtained are in agreement with the in vitro measurement of the B/A parameter. The results presented indicate that a simple scheme based on the measurement of attenuation effects associated with nonlinear sound propagation could provide a novel method for imaging tissues.
