Patent ID: 7709801

Claim:
A nuclear medicine diagnosis equipment, comprising: a scintillator block having a plurality of two-dimensionally and closely arranged scintillators, the scintillator block having a plurality of optically combined scintillator arrays in a depth direction of an incident γ ray with different decay times for an emitted light pulse; a photodetector for converting an emitted light pulse emitted in the scintillator block into an electrical signal; an incidence timing calculating device for calculating an incident timing in the scintillator array for the electrical signal outputted from the photodetector; a scintillator array identifying device for identifying a scintillator array, in a plurality of arrays, that has received the electrical signal outputted from the photodetector; and an incidence timing compensation device for discriminating whether compensation for an incidence timing calculated by the incidence timing calculating device is to be done or not corresponding to a scintillator array identified by the scintillator array identification device, and for compensating the incidence timing based on a result of discrimination.
