Abstract:
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; etching said selected number of bars; coating said etched bars with an epoxy of a selected index of refraction; laminating said etched bars together, wherein a thin polyester film loaded with a reflective material is disposed between adjoining scintillator bars, wherein said thin film defines a reflector, whereby an assembly of laminated bars having a layer of said 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 etched 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; etching said second group of said cut bars; coating said second group of etched bars with said epoxy of said selected index of refraction; laminating a second selected number of said second group of etched bars together, wherein a thin polyester film loaded with said reflective material is disposed between adjoining scintillator bars, wherein said thin film defines a reflector, whereby a detector array of discrete scintillator crystals having a reflector disposed between adjoining discrete scintillator elements is formed.
