Background variability % (a) and contrast recovery % (b) of NEMA image quality phantom measurements with 18F (black) and 68Ga (red). The five graphs in each column display the results of separate reconstruction methods; OSEM (3 iterations, 16 subsets, 5-mm Gaussian post-processing filter) and BSREM with β-values of 133, 267, 400, and 533. Both reconstruction methods included TOF and PSF recovery
