Abstract:
1. A method of manufacturing a radiation detector including scintillator groups having a plurality of scintillators in a two-dimensional close arrangement, a light guide optically coupled to the scintillator group, and a plurality of light-sensitive elements optically coupled to the light guide and smaller in number than the scintillator groups, said method comprising (1) a step of preparing a lattice frame by combining a plurality of plate-like optical elements into a lattice form; (2) a step of storing the lattice frame in a receptacle capable of storing the lattice frame, and further storing scintillators, to form a trial assembly, and taking the lattice frame and the scintillators once out of the receptacle in the state of trial assembly; (3) a step of pouring an optical binding material into the receptacle before storing the lattice frame and scintillators in the trial assembly in the receptacle; (4) a step of storing, the lattice frame and the scintillators in the trial assembly in the receptacle; (5) a step of allowing for adhesion and hardening in this state, and (6) a step of taking out of the receptacle a scintillator block integrating the optical binding material hardened, the lattice frame and the scintillators, and adjusting a contour thereof to complete the scintillator block.
