Reconstruction of the third case phantom (Fig. 4a[link]) with 80 projections instead of 800. (a) Result of the reconstruction using the filtered back-projection. (b) Result of the reconstruction using the Dictionary Learning technique, without rings correction, with parameters [\beta] = 0.05, [\rho] = 10. (c) Result of the reconstruction using the Dictionary Learning with rings correction, with parameters [\beta] = 0.05, [\beta_{r}] = 3×10-3, [\rho] = 10. (d) Result of the reconstruction using the Total Variation regularization with parameters [\beta] = 1, [\beta_{r}] = 0.05.
