Scintillation Camera Imaging with I-123

Abstract
I-n3 produced from 3 different nuclear targets (Te-122, Te-124 and T-127) was evaluated for spatial resolution and sensitivity with an Anger scintillation camera. Te-122 targets generated a substantial amount of I-130, which necessitated use of a medium-energy collimator. Te-124 targets produced solutions with significant amounts of I-124. Shortly after the end of bombardment, a 4000 hole (4KH) collimator was satisfactory; at 30 h, a medium-energy collimator was required. High purity I-123 from an I-127 target gave excellent spatial resolution when the 4KH collimator was used, but low-energy foil collimators were not adequate.
