Ultrasonic Stimulated Acoustic Emission for Detection of Breast Microcalcifications

Abstract

The purpose of this research is to develop an experimental imaging system based on Ultrasound Stimulated Acoustic Emission (USAE) for detecting microcalcifications in human breast tissue specimens. The scope of this research is to develop the theory, improve the experimental USAE system, and perform USAE imaging on human breast tissue samples. The first task of this research is focused on system development and optimization for detection of beast microcalcifications. The second task is centered on imaging breast tissues using USAE method for detection of microcalcifications. This report covers the entire project period including the results of Tasks I and 2. Results show that USAE can detect microcalcifications and calcified vessels. Results are verified using x-ray mammography. In addition to detection of microcalcifications, it is shown that USAE has may be used to determine the mechanical properties of the medium surrounding a small inclusion.
