(color online) Zoomed comparisons of FDK reference, SART-TV, ADTVM, and KL-TpV on sagittal and coronal sections. From the left to the right column the images are results of FDK (full views), SART-TV (sparse views, 60 projections), ADTVM (sparse views, 60 projections), and KL-TpV (sparse views, 60 projections, p = 0.92). Panels (a)–(d) and (e)–(h) are results of the 300^th and 275^th slice on the sagittal section. Panels (i)–(l) and (m)–(p) are results of the 160^th and 200^th slice on the coronal section. The gray scale of the displayed window is set to [0.01 0.06].
