摘要： The invention relates to the field of X-ray differential phase contrast imaging. For scanning large objects and for an improved contrast to noise ratio, an X-ray device (10) for imaging an object (18) is provided. The X-ray device (10) comprises an X-ray emitter arrangement (12) and an X-ray detector arrangement (14), wherein the X-ray emitter arrangement (14) is adapted to emit an X-ray beam (16) through the object (18) onto the X-ray detector arrangement (14).

摘要： The present invention relates to differential phase-contrast imaging of an object. For increasing spatial resolution of an X-ray imaging system (2) the size of a detector pixel element (8) may be considered a limiting factor. Accordingly, it may be beneficial to increase the resolution of an apparatus (38) for phase-contrast imaging without further reducing the area of an individual pixel element (8). Accordingly, an apparatus (38) for phase-contrast imaging with improved sampling is provided, comprising an X-ray source (4), a first grating element G1 (24), a second grating element G2 (26) and an X-ray detector element (6) comprising a plurality of detector pixel elements (8), each detector pixel element (8) having a pixel area A. An object to be imagined (14) is arrangeable between the X-ray source (4) and the X-ray detector element (6). The first grating element G1 (24) as well as the second grating element G2 (26) are arrangeable between the X-ray source (4) and the X-ray detector element (6). The X-ray source (4), the first grating element G1 (24), the second grating element G2 (26) and the X-ray detector (6) are operatively coupled for acquisition of a phase-contrast image of the object (14). At least one of the first grating element G1 (24) and the second grating element G2 (26) comprise a first area A1 having a first grating pitch p1 and a second area A2 having a second grating pitch p2 different from the first grating pitch.

摘要： X-ray devices for Phase Contrast Imaging (PCI) are often built up with the help of gratings. For large field-of-views (FOV), production cost and complexity of these gratings could increase significantly as they need to have a focused geometry. Instead of a pure PCI with a large FOV, this invention suggests to combine a traditional absorption X-ray-imaging system with large-FOV with an insertable low-cost PCI system with small-FOV, The invention supports the user to direct the PCI system with reduced FOV to a region that he regards as most interesting for performing a PCI scan thus eliminating X-ray dose exposure for scanning regions not interesting for a radiologist. The PCI scan may be generated on the basis of local tomography.
