an apparatus and method for fabricating a high performance reflective material for use on scintillator elements in a computed tomograph imaging device . adjacent scintillator elements are separated by gaps filled with a reflective coating layer . in one embodiment , the reflective coating layer consists of a surface level coating layer , an adhesion layer , a metallic reflective layer , and a top layer consisting of either a barrier coating layer or a polymeric encapsulant , or both . in another embodiment , the metallic reflective coating layer is applied to the scintillator element via an electroless metal deposition process utilizing a reducing agent and a metal complex . the ct reflectors formed by either embodiment have improved light output , minimized cross talk , higher geometric efficiency , and decreased performance degradation as compared with current ct reflectors that utilize organic binders and titanium dioxide fillers is achieved .
