| Outline of Final Research Achievements |
In our study, we showed that MRI(T2WI) signal intensity of area irradiated higher dose was changed higher intensity one year after carbon-ion radiotherapy for prostate cancer. We measured iso-center dose profiles of estimating dose in treatment planning system and iso-center signal intensity profiles of MRI(T2WI) scanned one year after irradiation. We analyzed both of profiles and we got the relationship among them. This study shows the possibility to develop the technology for estimating a real irradiated dose of particle therapy in a living body without invasive.
