| Outline of Final Research Achievements |
The purpose of this study is establishing the verification method of dose distribution in the human body using the anthropomorphic phantom based on patient CT. The 3D printer was used making patient specific anthropomorphic phantom to reproduce the tumor and body shape. The reproducibility of patient structure was verified by measuring the dose distribution.
The patient specific anthropomorphic phantom consists of two materials, a plaster bone which made by 3D printer and gelatin for the water equivalent tissue. The measured dose distribution at the air region in the body did not match the patient plan. But the gamma analysis with 3 mm/3 % was 95.4 % in an irradiation field. From these results, the method of this study could reproduce the body structures to the anthropomorphic phantom.
