In a, the recovery coefficients are plotted against the volumes of all spheres (0.52, 1.15, 2.57, 5.58, 11.49 and 26.52 ml) of the NEMA IEC Body Phantom filled with a sphere-to-background ratio of 16:1 (total activity of 680 MBq), which was imaged with 5 s per projection. Recovery coefficients are provided for CT-based (yellow) and isocontour-based sphere segmentation (green) shown in b
