Solid state radiation imager having a reflective and protective coating

A radiation imaging device comprising:

• an array of scintillator elements, said scintillator elements each having a first and a second end, said first and second ends being opposite one another, the surface of each of said first ends having uneven protrusions extending therefrom, the radiation incident on said device entering said elements through said first end;
• an array of solid state photodetectors, said photodetectors being optically coupled to said second ends of said scintillator elements to receive light therefrom;
• a moisture barrier comprising at least an optically reflective layer and a moisture sealant layer disposed over said optically reflective layer, said moisture barrier being substantially impervious to moisture and being optically reflective and radiation transmissive, said moisture barrier further being disposed at least over said first ends of said scintillator elements, forming a moisture resistant seal thereover;
• a pellicle layer disposed between said moisture barrier and the irregular surfaces of said first ends of each of said scintillator elements, said pellicle layer being disposed to form a stable surface to which said moisture barrier adheres, said pellicle layer extending between said uneven protrusions from said first surfaces of respective ones of said scintillator elements;
• and.
• a radiation transmissive window disposed over at least the portion of said moisture barrier overlying said first ends of said array of scintillator elements, said window providing a hardened protective surface over said moisture barrier
• a processing circuit coupled to receive signals generated by said photodetector array;
• and
• display and analysis equipment coupled to, and responsive to, said processing circuit.
