Abstract
A method of arranging detector modules within a gamma ray detector apparatus, each detector module including an array of scintillation crystals to convert light into electrical signals, the light being generated in response to incident gamma rays generated by an annihilation event, the method including obtaining performance information of each of the detector modules, and determining a relative location for each of the detector modules within the gamma ray detector based on the obtained performance information of the detector modules.

A method of arranging detector modules within a gamma ray detector apparatus, each detector module including an array of scintillation crystals to convert light into electrical signals, the light being generated in response to incident gamma rays generated by an annihilation event, the method comprising:
- obtaining performance information of each of the detector modules;
- and
- determining a relative location for each of the detector modules within the gamma ray detector based on the obtained performance information of the detector modules.
A gamma ray detector apparatus, comprising:
- a plurality of detector modules arranged to form a detector ring, each detector module including an array of scintillation crystals to convert light into an electrical signal, the light being generated in response to incident gamma rays generated by an annihilation event,
- wherein the detector modules are arranged within the detector ring based on a performance property of each of the detector modules.
