| Outline of Final Research Achievements |
In this research, a dynamic performance improvement of computer-assisted (CAD) detection software by considering diversity of image data due to imaging scanner or imaging parameters was investigated. We constructed a training method of CAD software using online transfer learning algorithm, and verified by multicenter data. We also investigated whether a simplified method of gold standards definition can be used as an alternative to gold standards defined by pixel-by-pixel painting for CAD software using voxel-based classification.
