Phantom sphere profiles. Transaxial line profiles through the centre of the 37-mm sphere (a, d, g), 22-mm sphere (b, e, h) and 13-mm sphere (c, f, i). Plots in the top row are for unfiltered images, those in the centre row are for post-filters to match voxel COV, and those in the bottom row are for plots to match SUVmax.
