CatPhan® 600 phantom image reconstructions by different algorithms from 63 projection views. Column (a) shows the reconstruction by the FDK method from the total 634 projection views as a reference. Column (b) shows the reconstruction by the FDK algorithm from 63 projection views. Column (c) shows the reconstruction by the AwTV-POCS algorithm from 63 projection views. Column (d) shows the reconstruction by the TV-POCS algorithm from 63 projection views. The bottom row shows the zoomed pictures. The displokay window of top row is [0, 0.024]. The display window of bottom row is [0.008, 0.02] mm−1.
