PROBLEM TO BE SOLVED: To provide an X-ray Talbot imaging apparatus capable of making a subject and a first grating closer to each other even when the subject is in a state such as being held by a holding tool.SOLUTION: An X-ray Talbot imaging apparatus 1* comprises: a plurality of gratings including phase gratings 14, 15 a radiation generator for irradiation of radiation and a radiation detector 16 for capturing a moire image. The imaging apparatus also includes: a phase grating protective member 14A located between the phase grating 14 and a subject H and protecting the phase grating 14 and a subject holding member 20 for holding the subject H in a position upstream or downstream of the phase grating 14 in the direction of an irradiation direction. The phase grating 14 or the phase grating protective member 14A is disposed in a position nearer to the subject H than a contact β between the subject holding member 20 and the device body.SELECTED DRAWING: Figure 7COPYRIGHT: (C)2017,JPO&INPIT【課題】被写体を保持具で保持する等した状態でも被写体と第1格子とを接近させることが可能なX線タルボ撮影装置を提供する。【解決手段】X線タルボ撮影装置1*は、位相格子14、15を含む複数の格子と、放射線を照射する放射線発生装置と、モアレ画像を撮影する放射線検出器16とを備え、位相格子14と被写体Hとの間に位置し、位相格子14を保護する位相格子保護部材14Aと、被写体Hを放射線の照射方向における位相格子14の上流側または下流側の位置に保持する被写体保持部材20とを有し、位相格子14または位相格子保護部材14Aが、被写体Hに対して、被写体保持部材20の装置本体との接点βよりも近い位置に配置されている。【選択図】図7
