Claims

[Scope of utility model registration request]

In a scintillation camera that includes a scintillator, a plurality of photomultiplier tubes that receive light from the scintillator, and a weighting/addition circuit that weights signals from the photomultiplier tubes, each input section is commonly connected; ,
Each output section is connected via a changeover switch, and the weighting from the weighting/addition circuit inputted to the input section has first and second position calculation circuits for processing signals. Features a scintillation camera.
