Recovery coefficients calculated using the MHS phantom as a function of sphere size for Amax (left column) and A50 (right column). The results are presented for the 18F-filled phantom with 1/8 (a, b) and 1/4 (c, d) sphere-to-background contrast ratios and for the 68Ge-filled phantom with a 1/8 contrast ratio (e, f). For each graph, RC values were computed for C-SC− and OC-SC+ acquisitions and for the different reconstruction settings
