TRANSMISSION SCANNING TECHNIQUE FOR GAMMA CAMERA COINCIDENCE IMAGING

摘要

Gamma-camera coincidence (GCC) imaging systems and methods include a pair of gamma camera imaging heads rotatable about a patient-longitudinal imaging axis. The imaging heads will each have a plurality of radiation opaque septa plates extending transversely relative to the imaging axis about which they locate. Adjacent ones of the septa plates are spaced apart along said imaging axis. At least one point source of radiation will thus be positionally fixed between a predetermined adjacent pair of the septa plates of one of the imaging heads so as to be concurrently rotatable therewith.
