PROBLEM TO BE SOLVED: To provide a particle beam shielding jig and a manufacturing method thereof capable of quickly and accurately determining an irradiation position and a shielding position of a particle beam according to the shape of each patient.SOLUTION: A particle beam shielding jig 1 is disposed between a particle beam R emission part 31 in a treatment device 3 using a particle beam R, and a patient 4 receiving irradiation of the particle beam R. The particle beam shielding jig 1 includes a device side installation part 21 installed in the periphery of the particle beam R emission region 311 in the emission part 31, an irradiated body side installation part 23 installed in the periphery of a particle beam R irradiation region 411 in the patient 4, an irradiation route 11 for causing the particle beam R to pass from the emission region 311 to the irradiation region 411, and a shielding part 24 disposed at a part of the irradiation route 11 for shielding the irradiation of the particle beam R onto a specific region of the patient 4.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】患者一人一人の形状に応じて、粒子線の照射位置及び遮蔽位置を迅速かつ正確に決定することができる粒子線遮蔽治具及びその製造方法を提供すること。【解決手段】粒子線遮蔽治具1は、粒子線Rを用いた治療装置3における粒子線Rの出射部31と、粒子線Rの照射を受ける患者4との間に配置される。粒子線遮蔽治具1は、出射部31における、粒子線Rの出射部位311の周辺に装着される装置側装着部21と、患者4における、粒子線Rの照射部位411の周辺に装着される被照射体側装着部23と、出射部位311から照射部位411へ粒子線Rを通過させる照射経路11と、照射経路11の一部に配置され、患者4の特定部位への粒子線Rの照射を遮る遮蔽部24とを備える。【選択図】図2
