摘要: According to one embodiment, a nuclear medicine imaging apparatus includes detector, calibrator, and an image reconstruction unit. The detector plurality of modules, each counting light originating from gamma ray. calibrator unit calibrates time information all the modules by calibrating for determining detection pair based on which approximately coincidentally count annihilation rays distance between in state point radiation source including positron emitting nuclide is installed position near predetermined modules. reconstructs using difference times corrected calibrated calibrator.
