Abstract: A mobile grating-detector arrangement has an X-ray detector and at least one grating. The grating-detector arrangement is configured to record an interferometric X-ray image of at least one body part of a patient in a patient bed in operation. In addition, an X-ray system with such a grating-detector arrangement and its use for X-ray interferometric imaging is described.

Abstract: A method and an X-ray apparatus generate a projective X-ray representation of an examination object. Two projective images obtained from a phase contrast measurement are adapted to each other in respect of their representation format and a result image is generated by combining the adapted images. The result image allows extensive separation of different structures in the examination object that is used.

Abstract: A method and an x-ray apparatus for interferometric 2D x-ray imaging, use a Talbot-Lau interferometer having at least one phase grating and an analysis grating for producing 2D images of an object to be examined using a phase stepping method. A stepwise readout of a detector is carried out continuously at a multiplicity of the phase positions of an interference pattern. Time sequences of readout interval data records which overlap in time are extracted from the readout data records, and at least one result image data record is calculated from an absorption image and/or a phase-contrast image and/or a dark-field image from each readout interval data record.
