| Outline of Final Research Achievements |
In breast cancer screening using mammography, due to the increase of the number of examinees, reading a lot of mammograms became burden for doctors, and it might lead to false detection and unnecessary biopsies. For reducing the work burden of doctors and improving their diagnostic accuracy, computer-aided diagnosis (CAD) systems have been developed. However, it is difficult to design the quantitative features that sufficiently represent the characteristics of abnormalities in mammograms for accurate diagnosis. To solve this problem, we have developed a new CAD system based on a deep learning technique that can extract such features through learning massive data sets. The experimental results showed that diagnostic sensitivity of a typical abnormality was about 90 % and false positive was 20 %. The results demonstrated that the proposed deep learning technique has a potential to be a key strategy for mammographic CAD systems.
