Reconstructed 3D image of a shale sample [46]. The input dataset consists of 90 projections each with 2K × 2K pixels. a, b The 3D reconstructed image using SIRT and Gridrec algorithms, respectively. Reconstruction with SIRT takes \(\sim\)353 s for 80 iterations, using two threads, reconstruction with Gridrec takes only \(\sim\)9 s, using one thread. However, SIRT with 80 iterations provides a higher-quality image than does Gridrec
