Table 4 Normalized RCmean for the number for iterative updates used in clinical reconstruction setups (and maximum RCmean values) obtained for the smallest sphere insert (diameter of 10 mm) and a medium size insert (diameter of 17 mm) characteristic of tested PET FDG procedures. Reconstruction protocol setups used in the clinic are labeled with (c)
