We have developed a stereoscopic mammography system using state-of-the-art digital technology that enables a mammographer to view the internal structure of the breast directly in depth. The primary aims of this project are to further develop and refine this system and then to evaluate its effectiveness in increasing the accuracy of diagnosis of breast cancer relative to the diagnostic accuracy afforded by standard, non-stereo film views. The expected increase in diagnostic accuracy could increase the yield of biopsy substantially by allowing the radiologist to more confidently recommend accelerated follow-up of truly benign disease and biopsy of truly malignant disease. Our accomplishments in Year 3 consist of progress in six areas 1 continued accrual of stereo mammographic images from enrolled patients, 2 development of computer- assisted methods for processing of the raw stereo mammographic images, 3 improvements to the user interface of the stereo display workstation, 4 further research on the design of a new stereo display workstation, 5 identification and development of new stereo-based visual features, and 6 design, conduction and analysis of a preliminary reading study.
