Claim One:
1. An X-ray device for imaging an object, comprising: an X-ray emitter arrangement, and an X-ray detector arrangement, wherein the X-ray emitter arrangement is adapted to emit an X-ray beam through the object onto the X-ray detector arrangement, wherein the X-ray beam is spatially at least partially coherent, wherein the X-ray beam is fan-shaped, wherein the X-ray detector arrangement comprises a phase grating and an absorber grating, wherein the X-ray detector arrangement comprises a detector for detecting X-rays, wherein the X-ray detector is an area detector, 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, wherein the object has a region of interest which is larger than a detection area of the X-ray detector and the X-ray device is adapted to generate image data of the region of interest by moving the object and the X-ray detector arrangement relative to each other, wherein the X-ray emitter arrangement comprises an X-ray source with switchable emitter lines, wherein the X-ray emitter arrangement, in a direction of relative movement, of the X-ray detector arrangement with respect to the X-ray emitter arrangement, that is orthogonal to the beam, is larger than the X-ray detector arrangement, wherein the X-ray device is adapted to switch the emitter lines such that solely the emitter lines opposite to the X-ray detector arrangement are switched on.
