Figure 6
Comparisons of the convergence performance of different iterative reconstruction algorithms based on 60-view noise-free projections (left) and 60-view noisy projections (right). The red line with circles, green line with triangles and blue line with rectangles represent the SART, SART-FAB4 and SART-FAB8 algorithms, respectively.
