Fig. 16. Scan of teeth without (A) and with (B) software beam hardening correction. In yellow, cupping artefacts increase the reconstructed density at the edges (see plots of gray values along the yellow lines) and decrease it in the centre of the object. In blue, streaking artefacts create dark or white lines between structures. Images by MNHN.
