Figure 2
N2I results for full, one-half, one-third, one-fourth and one-sixth dose images are shown with their corresponding equivalent simulated-dose reconstruction. All N2I outputs (bottom row) are considerably denoised compared with the filtered back projection reconstructions (top row). Notable streak artefacts are found in the one-sixth dose image (wavy lines/ripples), where a lack of projection data induces artefacts in the background.
