Claim One:
1. An X-ray device for imaging an object ( 18 ), comprising: an X-ray emitter arrangement ( 12 ), an X-ray detector arrangement ( 14 ), wherein the X-ray emitter arrangement ( 12 ) is adapted to emit an X-ray beam ( 16 ) through the object ( 18 ) onto the X-ray detector arrangement ( 14 ), wherein the X-ray beam ( 16 ) is at least partial spatial coherent, wherein the X-ray beam ( 16 ) is fan-shaped, wherein the X-ray detector arrangement ( 14 ) comprises a phase grating ( 50 ) and an absorber grating ( 52 ), wherein the X-ray detector arrangement ( 14 ) comprises a detector ( 54 ) for detecting X-rays, wherein the X-ray detector is an area detector ( 54 ), wherein the X-ray device is adapted to generate image data from the detected X-rays and to extract phase information from the X-ray image data, the phase information relating to a phase shift of X-rays caused by the object ( 18 ), wherein the object ( 18 ) has a region of interest ( 32 ) which is larger than a detection area of the X-ray detector ( 18 ) and the X-ray device is adapted to generate image data of the region of interest ( 32 ) by moving the object ( 18 ) and the X-ray detector arrangement ( 14 ) relative to each other.
