摘要： A pixilated scintillator array for a radiation detector of an imaging system includes a plurality of scintillator pixels arranged side by side in an array. The scintillator pixels are separated from adjacent scintillator pixels by gaps. Each scintillator pixels includes a top surface, a plurality of side surfaces, and a first layer covering the top surface and the side surfaces of each scintillator pixel. The first layer is formed from a smoothing coating. A second layer formed from a reflective metal coating covers the first layer, and a third layer formed from a barrier coating covers the second layer.

摘要： An apparatus and method for fabricating a high performance reflective material for use on scintillator elements in a computed tomograph (CT) 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.
