RC_max (left), RC_mean (middle) and RC_peak (right) for Gallium-68 from all five centres measured from the NEMA IQ phantom reconstructed with BPL₈₀₀ (solid lines) and PSF_6.4 for the GE scanners and PSF₅ for the Siemens scanner (dashed lines). The 2 RCs (dashed black lines) for the EARL 2 Fluorine-18 standards are also displayed as opposed to the limits proposed in this study for Gallium-68 (black solid lines)
