Abstract
Quantitataive images of selected acoustic parameters of tissues are obtained in cross sections through tissues and in vivo human female breasts. Methods of calculating acoustic speed, attenuation, and absorption under suitably defined assumptions and restrictions are described. Equations describing the relationship between the line integral of specific acoustic parameters within the tissue and measurable values on the received acoustic pulse are given including procedures for their implementation. Methods for solution of the acoustic tissue parameters using the reconstruction process are discussed. Results indicate that average acoustic speed is higher in breasts with cancer and with fibrocystic disease compared to normal breasts that acoustic speed is a function of age.
