PROBLEM TO BE SOLVED: To accurately and easily perform rough adjustment of gratings executed prior to fine adjustment by moire fringes, by means that does not use the moire fringes.SOLUTION: An X-ray imaging system includes an X-ray talbot imaging device and adjusting means for adjusting a position of gratings with respect to an X-ray irradiation axis. The adjusting means includes an alignment shape part provided to at least two gratings of a plurality of gratings or at least two grating holders for holding the at least two gratings respectively, which can be detected by ordinary X-ray imaging. The alignment shape part is located on the X-ray irradiation axis out of the at least two gratings or the at least two grating holders.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2019,JPO&INPIT【課題】モアレ縞による精密調整の前に行われる格子の粗調を、モアレ縞によらない手段によって高精度かつ簡便に行うことである。【解決手段】X線タルボ撮影装置と、X線照射軸に対する格子の位置を調整するための調整手段と、を備えたX線撮影システムであって、調整手段が、複数の格子のうち少なくとも二つの格子又は当該少なくとも二つの格子それぞれを保持する少なくとも二つの格子ホルダーに設けられ、かつ、通常のX線撮影で検出可能なアライメント形状部を有し、アライメント形状部が、少なくとも二つの格子又は少なくとも二つの格子ホルダーのうちの、X線照射軸上に位置している。【選択図】図6
