摘要:
Embodiments relate to an imaging system that includes a collimator assembly having one or more pinhole apertures therein. The imaging system is configured so that one or more of the pinhole apertures has an adjustable focal length. The imaging system further includes a detector assembly configured to generate one or more signals in response to gamma rays that pass through the one or more pinhole apertures. Embodiments also relate to methods of changing collimator performance and methods of imaging a volume.
