Abstract
An embodiment of the invention relates to an X-ray device, more particularly for phase-contrast imaging in the medical sector. In at least one embodiment, the X-ray device includes an X-ray radiation source, a coherence grid, a phase grid and an X-ray detector from a number of pixels arranged in a matrix, the pixels including a lens grid.
Claims16
An x-ray device, comprising:
- an x-ray radiation source;
- a coherence grating;
- a phase grating;
- and
- an x-ray detector made of a number of pixels disposed in a matrix-like manner;
- and
- a lens grating assembled from prisms, wherein the lens grating is disposed between the phase grating and the x-ray detector and the lens grating includes two sub-gratings arranged in an optical axis direction, of which a first sub-grating deflects x-ray beams which have experienced a phase shift by the phase grating and a second sub-grating deflects x-rays beams which passed the phase grating without being influenced.
