the same detector arrangement for angle-resolving detection of radiation and methods of operation

Detector arrangement (1) for angle-resolving detection of radiation with at least one detector element (2) having a front (3) and a back (4), a first detector material and a second detector material between the front face (3) and the back (4) wherein a space between the front (3) and the back (4) is filled out of the detector element (2) of a plurality of regions (6) from the first detector material and at least one region (5) from the second detector material and each area on the front ( 3) (with the back 4) of the detector element (2) connects, and wherein a collimating (by the front face 3) (in the detector element 2) incoming radiation (γ) made by the detector materials.
