| Outline of Final Research Achievements |
Construction of a radiation therapy system which can consider respiratory movement of tumor and organs. Location variation and irradiation time are also considered using the 2 axis of X-ray fluoroscopic motion tracking device that are installed at the proton therapy within the gantry. To enable image of the cone-beam CT to get the original source image of 4-dimensional CBCT (4D-CBCT) with the use of the motion tracking device and try to develop the principle and performs imaging test by phantom. Morphological changes of the patients on the treatment couch by imaging moving tumors and organs by 4D-CBCT, the appropriateness of the treatment planning time and compare present status of tumor irradiated and the condition of the normal tissues are to be verified.
