Fig. 4From: Impact of γ factor in the penalty function of Bayesian penalized likelihood reconstruction (Q.Clear) to achieve high-resolution PET imagesRelationship between CRChot and BV curves of hot spheres with diameters of 10, 13, 17, 22, 28 and 37 mm using BPL reconstructions with different γ factors. Curves for BPL run from left to right as β values decreaseBack to article page
