ABSTRACT:
The present invention is directed to an improved CT detector scintillator to photodiode optical coupling. The CT detector utilizes a controlled air gap between the photodiode array and the scintillator array together with an anti-reflective layer on the scintillator array. To improve the absorption of light at the photodiode array, the photodiode array includes a textured light reception surface. By incorporating a textured layer with the photodiode array, the light collection efficiency of the photodiodes is improved. The textured layer may extend along an x- and/or z-axis and the texturing may be in different forms. For example, the textured layer may include a series of pyramidally-shaped protrusions.
