CT Scans in Art Work Appraisal
A. CT: 3D opaque view of the head of a Khmer Buddha, Cambodia, 13th century. Sandstone, 45 cm.
B. CT: the same 3D view after adjustment of the display of visible densities to erase the restored part of the nose and diadem (arrows), thus simulating the appearance of the statue before restoration.
C. CT: two thin axial sections, one through the restored part of the diadem and the other through the nose, bringing out the difference in density between the sandstone and the material used for the restoration (arrows).
