ABSTRACT:
Embodiments relate to pinhole collimator assemblies having one or more adjustable size pinhole apertures therein. The pinhole collimator assembly is configured so that gamma rays can pass through the collimator assembly, but the remainder of the collimator assembly is substantially gamma ray absorbent. Embodiments also relate to imaging systems and methods of adjusting pinhole collimator performance.
