Radial net true sinogram profiles (all angles added) of a NEMA image quality phantom, filled with water solutions of several radioisotopes used for PET imaging: 68Ga (thick black line), 90Y (thin red line), 124I (thick red line), and 11C, 18F, 64Cu, and 89Zr (all in black dotted lines). The phantom was scanned on a Siemens mCT PET/CT scanner. The profile is shown after normalization to maximum, a in linear scale and b log scale
