  • Non-parallel grating arrangement with on-the-fly phase stepping, X-ray system
    Patent number: 8848863
    Abstract: The present invention relates to X-rayimage acquisition technology in general. Employing phase-contrast imaging for X-rayimage acquisition may significantly enhance the visibility of structures in images acquired. However, phase-contrast information may only be obtainable in a small detector region with subsequent image acquisitions requiring individual phase stepping states to allow reconstruction of an X-ray image. Accordingly, a grating arrangement for phase-contrast imaging is provided which may allow on the fly phase stepping during a field of view scan. According to the present invention a grating arrangement (1) for phase-contrast imaging is provided, comprising a first grating element (8) and a second grating element (10). Each of the first grating element (8) and the second grating element (10) comprises a trench structure. The trench structure comprises at least one trench region (9) and at least one barrier region (3).
