Reconstructions of data corrupted with zingers showing an example where the Shepp–Logan filter reconstruction and corresponding segmentation are better than those using an implementation-adapted filter or an iterative method (SIRT). (Top row) Reconstructions of data from slice 128 (Nθ = 512, no noise) corrupted with zingers. Zingers are more prominent in the reconstruction using an implementation-adapted filter and in the SIRT reconstruction (after 800 iterations). (Bottom row) Segmentations using Otsu's method of all three reconstructions. The Otsu threshold, F1 score and Jaccard index for each image is given below.
