Abstract: Post-patient collimators and methods of manufacturing post-patient collimators are provided. An example method includes additively manufacturing a collimator array having a plurality of tapered cavities, positioning a plurality of scintillator pixels within the tapered cavities of the collimator array, and hardening the pixels within the tapered cavities. An example post-patient collimator includes a collimator array including a plurality of cavities, wherein each of the plurality of cavities includes tapered walls, a scintillator including a plurality of pixels, each of the plurality of pixels positioned with one of the plurality of cavities of the collimator, and a reflector positioned on a top of each of the plurality of pixels.
