TRANSMISSION SCANNING TECHNIQUE FOR GAMMA CAMERA COINCIDENCE IMAGING

摘要

Gamma-camera coincidence (GCC) imaging system (10) and method include a pair of gamma camera imaging heads (12, 14) rotatable about a patient-longitudinal imaging axis (A1). The imaging heads (12, 14) each having a plurality of radiation opaque septa plates (12-1, 14-1) extending transversely relative to the imaging axis about which they rotate. Adjacent ones of the septa plates are spaced apart along said imaging axis. At least one point source of radiation (16) is positionally fixed between a predetermined adjacent pair of the septa plates (14-1a, 14-1b) of one of the imaging heads (14) so as to be concurrently rotatable therewith.
