Figure 8
Rhynie chert sample tomography acquired at ESRF ID19, with energy of 17.6 keV and pixel size of 1.52 µm. (a) Filtered back-projection with the correct rotation axis. (b) Correction with the RCP technique, using the parameters W = 10 and $[\theta_{0}]$ = 10. (c) Reconstruction with the Total Variation regularization using the incorrect rotation axis. (d) Reconstruction with the Total Variation regularization using the correct rotation axis. The parameters were $[\beta]$ = 3×10^-3 and $[\beta_{{r}}]$ = 3×10^-4.
