Breast cancer can be more easily treated and the treatment be more effective the earlier the cancer is discovered. It is estimated that a palpable tumor may has been in existence an average of seven years. According to the statistics published in the cover story of Time Magazine, January 14, 1991, one American woman in ten will get breast cancer, why and what can be done?Since then, the incidence rate has risen. On the basis of current rates, one out of eight women will be affected by this disease in their lifetime (Feuer, E.J. et. al., The life time risk of developing breast cancer, J. Natl. Cancer Inst., 85, pp. 892-897, 1993). It is a well-recognized health hazard. Any method which can aid in the discovery of suspicious growths at an earlier and smaller stage and before it becomes overt can have great benefit in reducing the human toll of breast cancer. Strong medical evidence has shown that early detection for breast cancer is crucial in order to save thousands of women's lives and the survival rate can be as high as 82%. RSSIPL is currently developing and investigating various effective computer-aided diagnostic (CAD) systems for detection, segmentation and classification of microcalcifications and masses. A joint effort of this research includes Dr. San-Kan Lee who is the Chairman of Diagnostic Radiology in Taichung Veterans General Hospital in Taiwan and Professor Pau-Choo Chung with the Department of Electrical Engineering at National Cheng Kung University, Tainan, Taiwan. Our goal is to focus on breast cancer early detection and develop computer-aided design (CAD) screening systems for clinical applications. So far, we have developed two prototype CAD systems which will be integrated with the existing Picture Archiving and Communication System (PACS) currently implemented in Taichung Veterans General Hospital. One is a mammography screening system which has been filed by UMBC for a patent. Another is a 3-D surgical navigation system that can be used to localize clustered microcalcifications for surgical navigation for needle biopsy. It already patented in Taiwan and is currently filed by National Science Council in Taiwan for a US patent.
