Abstract

Various embodiments described herein may include a detector array for a CT imaging system. The detector array includes a pixel array in which each pair of adjacent pixels in the pixel array may be separated by a collimator (e.g., located between each row and column of the pixel array) that absorbs photons and each pixel in the pixel array includes a sub-pixel array. The collimator absorbs photons that strike at a boundary between adjacent pixels. Each sub-pixel may have an anode that is connected to an ASIC channel. When a sub-pixel in a pixel detects a photon, signals of a plurality of sub-pixels in the pixel are automatically summed, including the sub-pixel that detected the photon.
