DETECTOR COMPONENT FOR AN X-RAY OR GAMMA RAY DETECTOR

There is provided a detector component (40) for an X-ray or gamma ray detector, the detector component (40) comprising: a scintillating crystal having a plurality of scintillation crystal pixels (41), wherein each scintillating crystal pixel (41) is larger in one dimension than in the other two dimensions, and wherein each scintillating crystal pixel (41) has one or more light exit faces; and a photodetector (42) associated with at least one of the light exit faces of each scintillating crystal pixel (41), wherein a first and a second scintillating crystal pixel are arranged adjacent to one another, wherein a X-ray or gamma ray interaction with the first scintillating crystal pixel causes the generation of at least one photon, and optical cross talk of the at least one generated photon occurs between the first and the second scintillating crystal pixel, such that the X-ray or gamma ray interaction within the first scintillating crystal pixel is detected in use at the photodetector associated with a light exit face of the second scintillating crystal pixel.
