CRYSTAL ELEMENT ASSEMBLY, ELECTRICAL CIRCUIT THEREFOR, NUCLEAR MEDICINE DIAGNOSTIC DEVICE USING THEM, AND ENERGIZATION CONTROL METHOD

PROBLEM TO BE SOLVED: To provide a nuclear medicine diagnostic device excelling in energy resolution and a nuclear medicine diagnostic method. SOLUTION: This nuclear medicine diagnostic device has a bonded structure made by bonding a semiconductor element S and conductive members 22A, 22B, 23A, and 23B with conductive adhesion material 24 composed of conductive particles and a resin binder. This device is equipped with a structure in which electric charge is picked up as a signal from the conductive members 22A, 22B, 23A, and 23B, via the adhesion material 24, through a detection circuit 40, the electric charge being induced when γ rays enter the semiconductor element S, and an energization control means 30 for passing an electric current through at least the adhesion material 24, the electric current being larger than an electric current caused by the electric charge induced when the γ rays enter.
