Figure 1From: Impact of point spread function modelling and time of flight on FDG uptake measurements in lung lesions using alternative filtering strategies 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.Back to article page
