Fig 3. Zoomed-in images of the low-dose protocol data for respiratory phase one.

Reconstructions were performed with L1-PICCS, TV-PICCS, and WT-PICCS for α equal to 0.2, 0.5, and 0.8, for 120 projections and X-ray flux corresponding to a number of photons I ₀ = 4.5∙10⁴. Arrows point at locations where differences in texture are more noticeable.
