PROBLEM TO BE SOLVED: To reliably and easily shield light of gaps between detector modules.SOLUTION: Support parts 51ra, 51rb for supporting shielding members 61 which cover gaps 51 g between detector modules 51 formed when a plurality of detector modules 51 are arranged are provided on the side opposite radiation incident surfaces in the detector modules 51. Also, the shielding members 61 formed in such a form as being supported by the support parts 51ra, 51rb are attached to the support parts 51ra, 51rb to cover the gaps 51 g between the detector modules 51.COPYRIGHT: (C)2013,JPO&INPIT【課題】検出器モジュール間の間隙を確実にかつ容易に遮光する。【解決手段】検出器モジュール51における放射線入射面の反対側に、複数の検出器モジュール51を配列したときに形成される検出器モジュール51間の間隙51gを覆う遮光部材61を支持するための支持部51ra,51rbを設ける。また、上記支持部51ra,51rbによって支持されるような形状に形成された遮光部材61を、支持部51ra,51rbに装着して、検出器モジュール51間の間隙51gを覆う。【選択図】図2
