Abstract : This is a progress report that summarizes activity in the two areas of the fellowship: (1) Diagnostic Imaging/ Mammography Certification and (2) Dissertation research on Breast Imaging using Ultrasound Diffraction Tomography techniques. The first task included academic clinical rotation courses in various imaging modalities at the UCI Medical Center as well as participation in mammography training and clinical trials at UCSD. A MS degree in Radiological Sciences was granted in March, 1995. Quality assurance tests of diagnostic imaging equipment including mammography systems and radiation shielding evaluations were carried out at several institutions. Dissertation research focused on the performance of two ultrasound diffraction tomography systems developed for breast imaging. Experiments using phantoms and tissue-mimicking materials were carried out to characterize system imaging performance in terms of resolution, contrast and dynamic range. Preliminary results on breast tissue ultrasound scatter characterization are reported.
