Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, many Computer Aided Diagnosis (CAD) systems are suggested. Those systems will be able to diagnose instead of a doctor, thus they will be expected to reduce heavy burdens on the doctor during diagnosis. The purpose of this study is to improve detection sensitivity for masses reducing the number of false positives. In the proposed method, we focused on brightness and density of masses, thus we applied mean shift segmentation. After the segmentation, we obtained concentration of gradient vectors using Iris-Filter and detected mass regions. According to the field test with a doctor, the proposed system was tested with 91 mammograms containing 60 masses. In the result of a performance test, a sensitivity of 91.7% was obtained at 1.57 false positives per image.
