Top panel—axial views of the cylinder phantom reconstructed using GE-OSEM, Q.Clear and Q.ClearRDP (96i1s). The purple line defines the cross section presented in the bottom panel, while the dashed contour corresponds to VOI_inside. Bottom panel—cross section through the cylinder phantom images reconstructed with GE-OSEM (A), Q.Clear (B) and Q.ClearRDP (C) for different numbers of iterations and 1 subset. The black continuous and dashed rectangular functions represent the ideal and the VOI_inside profiles, respectively
