Fig. 1From: Phantom-based image quality assessment of clinical 18F-FDG protocols in digital PET/CT and comparison to conventional PMT-based PET/CTBGcal as a function of the number of iterations used in the iterative reconstruction setups without Gaussian smoothing (a) and comparison of Gaussian vs. non-Gaussian setups (c) for devices that used the Gaussian smoothing in the clinic. Similarly, we reported BGcal as a function of the time per bed position (b and d). Digital devices were labeled with full lines; dashed lines represent obtained results with analogue devicesBack to article page
