Reconstructed images of the Derenzo hot-rod phantom from three different setups for conventional scanners (Clinical_3.18, Arb_1.6RR150 and Arb_1.6RR185) and our proposed system with two acquisition modes (AS-3 and AS-5). All images were reconstructed with 50 iterations and with a post-processed 3D Gaussian filter with sigma equal to 1 pixel. The phantom images were summed axially (28 slices for the Clinical_3.18 configuration and 55 slices for the others).
