Abstract
The present invention relates to X-ray differential phase-contrast imaging, in particular to a deflection device for X-ray differential phase-contrast imaging. In order to provide differential phase-contrast imaging with improved dose efficiency, a deflection device () for X-ray differential phase-contrast imaging is provided, comprising a deflection structure () with a first plurality () of first areas (), and a second plurality () of second areas (). The first areas are provided to change the phase and/or amplitude of an X-ray radiation; and wherein the second areas are X-ray transparent. The first and second areas are arranged periodically such that, in the cross section, the deflection structure is provided with a profile arranged such that the second areas are provided in form of groove-like recesses () formed between first areas provided as projections (). The adjacent projections form respective side surfaces () partly enclosing the respective recess arranged in between. The side surfaces of each recess have a varying distance () across the depth () of the recess.
