Figure 1

Hot and cold sphere phantoms. The figure shows transverse slices passing through the spheres' center for the different acquisitions with reconstructions of four iterations × eight subsets. Slices are shown for general information; the purpose of the study is for quantitative distribution assessment instead of diagnostic imaging. The true activity distribution is represented with the same voxel size than the reconstructions.
