Anthropomorphic torso phantom reconstructions by different approaches from the 58-views projection data.

<p>(A) is the image reconstructed by the FBP approach with ramp filter; (B) is the images reconstructed by the PWLS-PICCS approach () using <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0079709#pone-0079709-g003" target="_blank">Fig. 3C</a> as the prior image; (C) is the images reconstructed by the PWLS-RPICCS approach () using <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0079709#pone-0079709-g003" target="_blank">Fig. 3E</a> as the prior image; and (D) is the image reconstructed by the PWLS-ndiTV approach () using <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0079709#pone-0079709-g003" target="_blank">Fig. 3C</a> as the prior image. All the images are displayed in the same window [0, 0.024].
