Abstract
Static (dose calibrator) assays of 82Rb bolus yield erroneous estimates of administered activity by ignoring the asymmetric output of 82Sr/82Rb generators. Though on-line monitoring of elution profile improves accuracy for quantitative purposes, it requires an elaborately shielded detector and associated electronics at patient-study site. Our alternative approach based on mathematical description of the dynamic characteristics of the generator accurately predicts elution profiles over a broad range of flow rates.
