Fig. 4From: 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)CRpeak and CRmax. Peak contrast recovery (CRpeak; upper row) and maximum contrast recovery (CRmax; lower row) are displayed for all reconstruction algorithms at the three signal-to-background ratios (SBR) as a function of sphere diametersBack to article page
