Abstract
Limited-angle (180° ) data collection is often used in single-photon emission tomography despite the theoretical superiority of 360° sampling. Three data collection protocols (using 180° and 360° projections) were evaluated in a computer-based simulation of myocardial infarction imaged with technetium-99m pyrophosphate. The reconstructions were evaluated by the sum-of-squares error (SSE) and lesion size accuracy tests. The 360° protocol gave the best SSE value; the lesion sizing results were equivocal.
