SNRs for different number of LORs and source-volume sizes. The OOC phantom described in “Phantoms” section is reconstructed with different numbers of LORs to determine the minimum number of LORs needed for an adequate image quality. The hot parts of the phantom are sphere-shaped volumes with radius ranging from 0.4 to 0.7 mm leading to the volume sizes used in the figure
