Abstract:
A finished detector module assembly suitable for use in a computed tomography (CT) imaging system, said detector module comprising:a substrate; a photosensor array mounted on the substrate; an array of scintillators optically coupled to said photosensor array and separated therefrom by a gap, said gap filled with a compliant clear film positioned distanced from at least one of said array of scintillators and said photosensor array less than one-half of a wavelength of light emitted by said scintillators; a clamping mechanism clamping said array of scintillators in place above and aligned with said photosensor array, wherein said clamping mechanism has a thermal coefficient of expansion less than that of said substrate; and a flexible electrical cable electrically coupled to the photosensor array.
