| Outline of Final Research Achievements |
In the radiotherapy for the thoracoabdominal region, it is important to evaluate the tumor and organ motion due to respiration in order to avoid unnecessary exposure to healthy organ. In such case, 4D-CT image has been used. However, 4D-CT exposes a very high dose for the subject. We develop the tumor motion analysis method using 4D-MR image and motion prediction method for radiotherapy.
Additionally, virtual 4D-CT generation method for planning of radiation dose distribution was developed.
