<p>PROBLEM TO BE SOLVED: To provide a detector capable of precisely measuring both timing measurement and energy detection.SOLUTION: A PET device includes a ring-shaped gantry (rack), a cradle (bed), and a computer for operation. The gantry includes a plurality of built-in detectors to be placed around a living body. The detector is configured by combining a scintillator and a photodetector. A first reflector RF1 surrounding a light-sensitive area is placed between a photodetector D1 and a scintillator SC, and a second reflector RF2 is placed between optical transfer areas of the scintillator.</p> |
