Outline of Final Research Achievements

A web-based database system has continuously been developed for studying organ motion estimated by real-time tumor-tracking radiotherapy (RTRT) and analysis of organ motion is performaed by using this database sytstem. The interface to reduce the artifact of organ motion is implemented and algorithm of organ motion modeling is developed.
