Fig. 3From: Evaluation of block-sequential regularized expectation maximization reconstruction of 68Ga-DOTATOC, 18F-fluoride, and 11C-acetate whole-body examinations acquired on a digital time-of-flight PET/CT scannerNoise measured in normal liver tissue for 68Ga-DOTATOC (a), 18F-fluoride (b), and 11C-acetate (c), respectively, using BSREM and OSEM (3 iterations, 16 subsets, 5-mm Gaussian post-processing filter). Both reconstruction methods included TOF and PSF recoveryBack to article page
