Abstract
A detector assembly for a CT imaging system is provided. The detector assembly including a scintillator block including a plurality of pixels, each pixel configured to receive x-ray beams travelling in a transmission direction, a plurality of photodiodes, and a light guide coupled between the scintillator block and the plurality of photodiodes, the light guide including a plurality of light pipes, each light pipe configured to guide light emitted from a pixel of the plurality of pixels into an associated photodiode of the plurality of photodiodes, wherein each pixel has a first cross-sectional area that is substantially perpendicular to the transmission direction, wherein each photodiode has a second cross-sectional area that is substantially perpendicular to the transmission direction, and wherein the first cross-sectional area is different from the second cross-sectional area.
