Abstract
A computer-based scintillation camera was designed for both dynamic and static radionuclide studies. The detecting head has 254 independnet NaI crystals, each with a photomultiplier and amplifier. In dynamic measurements simultaneous events can be recorded, and 1 million counts/s can be accommodated with less than 0.5% loss in any 1 channel. This corresponds to a calculated deadtime of 5 ns. The multidetector camera is being used for 133Xe dynamic studies of regional cerebral blood flow in man and for 99mTc and 197Hg static imaging of the brain.
