Abstract
NDE (Nondestructive Evaluation) of wood was performed using X-ray CT technique in
order to determine the applicability of this technology to ancient wooden buildings in the field. Two
main objectives were studied to consider applicability as well as accuracy. First, the most suitable
number of radiographs for reconstructing proper X-ray CT images was determined. Secondly, X-ray
CT images using SIRT were reconstructed using various numbers of radiographs in order to consider
the possible effects of absent projection data in field applications. As a result of this study, 9
radiographs were determined to be the most suitable number for this application. Brown-rotted part in
wood was also detected by X-ray CT images using 9 radiographs. It was concluded that even there
exists some absent projection data, CT images can be reconstructed with high accuracy.
