Outline of Final Research Achievements

The purpose of this study is to develop an auto-contouring system using anatomical and functional change due to a difference of measurement method of linear attenuation coefficient. The system can contour automatically a region with highly accurate and precise level because of considering physical change but not the experience. It is suggested that the system could contour automatically a region which has no atlas or information on functionality such as tumor.
