| Outline of Final Research Achievements |
The changing of target range by respiratory motion is one of the reason for losing the dose conformity in particle therapy. The goal of this study is making a deformable chest phantom by respiration which gives the new verification method in such respiratory tumors.
The shape of chest phantom is built by 3D printer, and the deformation and tumor movement with respiration is reproduced by compressed air control and motor. The chest phantom is virified with 4DCT and proton beam.

| Academic Significance and Societal Importance of the Research Achievements |
本研究で作成したファントムは、線量均一性の評価や呼吸同期照射における照射ゲートの設定評価などの品質管理に利用可能である。また、近年注目されている強度変調粒子線治療においても利用可能であり、粒子線治療における呼吸性移動を伴う腫瘍の治療において、より精度の高い品質管理が可能となる。
