Figure 3
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. Panels (a)–(d), (e)–(h) and (i)–(l) are reconstructed images under few-view, limited-angle and low-dose noisy limited-angle conditions, respectively. The blue arrow denotes streak artefacts; the green arrow denotes limited-angle artefacts. The pixel values of the above greyscale images were normalized to the range [0, 255]. The display window is [0, 255].
