Fig. 2From: Reconstructed spatial resolution and contrast recovery with Bayesian penalized likelihood reconstruction (Q.Clear) for FDG-PET compared to time-of-flight (TOF) with point spread function (PSF)Sphere activity profiles (13 mm). Radial activity profiles of the 13 mm sphere are displayed for signal-to-background ratio (SBR) 8:1 with the respective reconstructed spatial resolution (full width at half maximum, FWHM)Back to article page
