The present invention is directed to an integrated scintillator and collimator array for a CT detector. The integrated scintillator and collimator are fabricated from a manufacturing process or technique whereupon an array of scintillator material is positioned on a tooling base such that a collimator mold housing having a collimator mold therein may be positioned on the block of scintillator material. The block and mold housing are then aligned allowing a collimator mixture to be disposed into the mold. The collimator mixture is then allowed to cure to form an integrated scintillator and collimator.
