| Abstract(in English) | This paper describes improvements of breast cancer detection system for three dimensional (3D) breast CT images. To improve the performance of classification in this system, we have increased number of features from 237 to 520 and developed a new classifier using Support Vector Machine so as to improve discrimination accuracy. In order to evaluate performance of the improved system, we applied the system to thirty five multi-slice CT images (including 34 cancers) and achieved 94.1% sensitivity with an average of 0.06 false positive detection per image, which is 5.9% sensitivity improvement and 0.31 false positive reduction. |
