| Outline of Final Research Achievements |
The purpose of this study is to establish the Gradient method which is a new analysis method considering the dose gradient as a dose distribution evaluation method using film in radiation therapy. Generally, since radiation measurement follows Poisson statistics, we proposed a statistical based judgment criterion. In order to make statistical evaluation possible, we developed a method to evaluate uncertainty caused by measurement and misalignment, and verified by actual measurement at multiple facilities.
