Reconstruction results for the HPFcere2 dataset comparing the results obtained with extended iterations with SIRT and OS-SIRT 5 (intensity windowing was applied in each to boost contrast). The number of projections was 61, the tilt angle 120° and the volume size 356×506×148. We observe by visual inspection that 20 iterations with SIRT yield similar results than 6 iterations with OS-SIRT, but at double the wall-clock time. The relaxation factor λ was set to 1.0 for both SIRT and OS-SIRT 5.
