Patent ID: 7355180

Claim:
A method of manufacturing a radiation detector having a scintillator array formed of a plurality of scintillators in a compact, two-dimensional arrangement, a light guide optically combined to said scintillator array, and a plurality of photomultiplier tubes smaller in number than said scintillators and optically combined to said light guide, said method comprising: (A) a step of fabricating a lattice frame by combining a plurality of plate-like optical elements crosswise; (B) a step of pouring a transparent liquid resin into a rectangular vessel for receiving said lattice frame, before or after placing said lattice frame in said rectangular vessel; (C) a step of placing the scintillators in the rectangular vessel after placing the lattice frame in the rectangular vessel and pouring said liquid resin into a rectangular vessel; and (D) a step of removing from said rectangular vessel a cured resin object integrating the liquid resin having cured, the lattice frame and the scintillators, and contouring the resin object to make said scintillator array; said steps (A)-(D) being executed to manufacture said scintillator array.
