124I activity concentration in the phantom’s spheres as a function of increasing 131I activity in the background measured on the PET image reconstructed with the OSEM algorithm with 2 iterations and 16 subsets, TOF information and PSF modeling. The phantom was placed in the middle of the field of view (a) and on the scanner table at the anterior most position, 11.2 cm higher (off-center) (b)
