ラの検出器。[Claims for Utility Model Registration] 1. A disc-shaped scintillator, a collimator for projecting gamma rays emitted from a subject onto the scintillator, and a collimator optically joined to the scintillator via a light guide, In a scintillation camera detector consisting of a large number of photomultiplier tubes arranged in a square honeycomb shape and a cylindrical container housing them, the photomultiplier tubes are arranged in a honeycomb shape. Among the photomultiplier tubes, at least the photomultiplier tubes that should be lined up in a row on the outer periphery of one side of the hexagon are removed, and the scintillator and the container are arranged in the same position as the portion from which the photomultiplier tubes are removed. A detector for a scintillation camera, characterized in that a circular portion is formed along an array of photomultiplier tubes by cutting out a portion. 2. The photomultiplier tubes are arranged in an arrangement in which photomultiplier tubes arranged in a row on the outer periphery of a pair of opposite sides of the hexagon are removed from the photomultiplier tubes arranged in a honeycomb shape. scintillation camera detector.
