Abstract

The present invention relates to a method for producing an image of a target using radiation and a diffraction grating and apparatus for x-ray imaging. The method comprises directing a beam of radiation to the target to produce a modified beam through interaction with the target, directing the modified beam to an diffraction grating to produce an interference pattern, detecting the interference pattern using a detector, and forming an image of the target using the interference pattern measured. According to the invention, the diffraction grating is modified n the plane of the grating during the imaging so that at least two interference patterns are detected using the detector different configurations of the diffraction grating. Further, the image of the target using the at least two interference patterns measured. The invention provides a simple configuration, less radiation exposure and/or better image quality then conventional imaging methods.
