The present invention relates to a process of positional deviation in the X-ray imaging system for imaging differential phase contrast. The differential phase-contrast imaging system, in order to provide relief for preconditioning and regulatory requirements for the production and maintenance, the detector 16 of the X-ray source 14 and X-ray, the source grating 20, a phase grating 22, and analysis a grating 24, a source grid disposed between the X source and the phase grating, the analysis grid is placed between the detector and the phase grating, the differential phase contrast setup 12 comprising the grating arrangement 18 with, the X-ray imaging system 10 is provided for imaging differential phase contrast. Furthermore, the moving arrangement for the relative movement between at least one grating and the object under examination is provided, the translation arrangement 34 for translating the processing unit 32, and the source grating is also provided. Phase grating, analysis grating, and detector are provided as a fixed interferometer units in which the analysis grid and phase grating is mounted parallel to each other in the interferometer unit 36. The source grid, such Moire fringes can be detected in the plane of the detectors is positioned deviated from the interferometer unit. The processing unit detects a moir pattern in the signal provided by the detector when the X-ray radiation. The processing unit further calculates a translational signals 38 for translating the source grating in order to achieve a predetermined moire pattern. Translation arrangement is based on the value of the translation signal, it adjusts the position of the source grating at least in the X-ray projection direction 30.本発明は、微分位相コントラスト撮像用のX線撮像システムにおける位置ずれの処理に関する。微分位相コントラスト撮像システムにおける、製造及びメンテナンスのための事前調整及び調節の要件の軽減を提供するために、X線源14及びX線の検出器16と、ソース格子20、位相格子22、及び分析格子24を有し、ソース格子はXソースと位相格子との間に配置され、分析格子は位相格子と検出器との間に配置される、格子アレンジメント18とを具備する微分位相コントラストセットアップ12を有する、微分位相コントラスト撮像用のX線撮像システム10が提供される。更に、検査中の
