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.
Claims22
A detector arrangement for performing phase-contrast measurements, comprising
- at least two transducer layers formed of transducer material and arranged behind one another, at least a first of the at least two transducer layers arranged in a radiation direction including alternate sensitive areas, the alternate sensitive areas including sensitive areas with a relatively high absorption for the conversion of incident ray quantas into signals and less sensitive areas with a relatively lower absorption.
