Abstract:
1. A device for phase contrast imaging of an object, the device comprising: first, second, and third independently movable sliders; a source connected to the first slider and configured to issue an X-ray beam having an optical axis for producing absorption-based and phase contrast images; a detector connected to the second slider and configured to detect the X-ray beam; and a grating arrangement including a plurality of gratings connected to the third slider between the object and the source and between the object and the detector for moving out of the optical axis of the X-ray beam to produce the absorption-based images, and within the optical axis of the X-ray beam to produce phase contrast images; an input device configured to select a region-of-interest within the absorption-based image; a variable aperture configured to adapt a field-of-view of the X-ray beam to the region-of-interest on the phase contrast images.
