Figure 4
Enlarged regions of the reconstructed images of the LC phantom using the FBP (a,e,i), SART (b,f,j), AwTV-POCS (c,g,k) and AwaTpV-POCS (d,h,l) algorithms from 60-view projections under few-view, limited-angle and low-dose noisy limited-angle conditions, respectively. The magnified images were from the same regions in the reconstructed images, as marked with the green rectangle in Fig. 2(a)

. The pixel values of the above greyscale images were normalized to the range [0, 255]. The display window is [0, 255].
