The purpose of this research is to build an experimental system based on Ultrasound Stimulated Acoustic Emission for in vitro imaging of breast tissue specimens, with the goal of detecting microcalcifications with sufficient accuracy. The scope of this research is to improve the laboratory system and evaluate its performance on phantoms and specimens of human breast tissues containing microcalcifications. The first task of this research, which covers a part of the second year, focuses on system improvement for detection of breast microcalcification. The second task which also covers a part the second year, focuses on imaging breast tissue samples using ultrasound stimulated acoustic emission method. Our findings include improving our experimental system by substantially reducing the acoustic noise and increasing the scanning speed. Also, we have demonstrated that our method is capable of detecting small breast microcalcifications in human breast tissue samples. We have verified our results with x-ray mammography, and histology.
