Abstract

A detector arrangement is disclosed for performing phase-contrast measurements, including at least two transducer layers arranged one behind the other, wherein at least the first transducer layer arranged in the radiation direction includes alternate sensitive areas having a high absorptance for the conversion of incident radiation quanta into signals and less sensitive areas having a lower absorptance in comparison thereto. Further, a corresponding X-ray tomography device and a method for performing phase-contrast measurements are also enclosed.
