(color online) Comparisons of reconstructions given by (a), (d), (g) SART-TV, (b), (e), (h) ADTVM, and (c), (f), (i) KL-TpV (p = 0.92) on transverse section with 60 views. From the top to the bottom row, the images are results in the 72^th, 192^th, and 302^th slice of the transverse section. The gray scale of the displayed window is set to [0.01 0.06].
