- W1990291231 abstract "This study aims to evaluate the potential for using image gatingtechniques for accurate estimating random noise in clinical SPECT images.Phantom and patient bone SPECT scans were acquired in a gated mode usingstandard acquisition protocols with a dummy electronic trigger. The acquiredprojection data was divided into time slots and reconstructed using the samealgorithm to produce independent sets of data. Our results showed that thismethod can be used for accurate estimation of the level of random noise inphantom and clinical SPECT studies, and it avoids the problem of pixel valuecorrelation faced when using small ROI in estimating noise in SPECT images." @default.
