Patent ID: 7157014

Claim:
A method for producing a high resolution detector array, said method comprising the steps: cutting a first selected number of bars of scintillator material to a selected dimension; polishing said selected number of bars; coating said polished bars with an adhesive of a selected index of refraction; laminating said polished bars together, wherein a thin reflective optical film is disposed between adjoining scintillator bars, wherein said optical film defines a reflector, whereby an assembly of laminated bars having a layer of said optical film between adjoining bars is formed; allowing said laminated assembly to cure; cutting a second group of said selected number of bars from said laminated assembly, wherein said cut is perpendicular to said polished bars, whereby each of said second group of cut bars comprises a laminated composite of said selected number of scintillator elements having a reflector interposed between adjoining scintillator crystals; polishing said second group of said cut bars; coating said second group of polished bars with said adhesive of said selected index of refraction; laminating a second selected number of said second group of polished bars together, wherein a thin reflective optical film is disposed between adjoining scintillator bars, wherein said thin optical film defines a reflector, whereby a detector array of discrete scintillator crystals having a reflector disposed between adjoining discrete scintillator elements is formed.
