Title: DETECTOR ARRANGEMENT FOR AN X-RAY PHASE CONTRAST SYSTEM AND METHOD FOR X-RAY CONTRAST IMAGING
Abstract:
The present invention relates to a detector arrangement for an X-ray phase contrast system (5), the detector arrangement (1) comprising: a scintillator (11); an optical grating (12); and a detector (13); wherein the optical grating (12) is arranged between the scintillator (11) and the detector (13); wherein the scintillator (11) converts X-ray radiation (2) into optical radiation (3); wherein the optical grating (12) is configured to be an analyzer grating being adapted to a phase-grating (21) of an X-ray phase contrast system (5); wherein the optical path between the optical grating (12) and the scintillator (11) is free of focussing elements for optical radiation. The present invention further relates to a method (100) for performing X-ray phase contrast imaging with a detector arrangement (1) mentioned above. The invention avoids the use of an X-ray absorption grating as G2 grating in an X-ray phase contrast interferometer system.
