The present invention relates to a nuclear medicine diagnosis equipment comprising a scintillator block having a plurality of scintillators, the scintillator block having a plurality of scintillator arrays in a depth direction of an incident γ ray with different decay times for an emitted light pulse; an incidence timing calculating device for calculating an incident timing in the scintillator array; a scintillator array identifying device for identifying a scintillator array, in a plurality of arrays, that has received the electrical signal; and an incidence timing compensation device in a position arithmetic processing part 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 part.
