Outline of Final Research Achievements

It has been considered that use of both mammography and ultrasonography is effective for breast cancer screening. However, multimodality screening will increase radiologists’ workload. This study aims to develop a computer-aided diagnosis system for multimodality breast image reading for improving diagnostic efficiency.
For retrieving reference images that can be useful for diagnosis of new lesions, more relevant images could be selected by use of both mammograms and ultrasound images than by single modalities. We have also investigated the automated lesion detection on automated whole breast volume scans. The result of the automated detection can be used for automatic assignment of corresponding lesions on mammograms and ultrasound images.
