| Research Abstract |
This inter-disciplinary research was made possible by cooperation from researchers from both literary and scientific fields, and aimed to develop a preservation and restoration method for wooden cultural assets, especially Buddhist sculptures, using medical-use x-ray CT scanner. The biggest advantage of the x-ray CT scanning method is that it allows one to obtain information on the inner structure of cultural properties without physical contact, and thus without risking damage to the actual property. The method is especially effective in cases where the original state of the property is unknown due to restoration activities from later periods. Specifically, by reconstructing slice images from CT scanning, the researchers were able to recreate the original state on the computer monitor. Furthermore, not only does the method provide hints on the time period at which the property was created, but also allows one to examine whether there are any objects concealed within the sculpture, and in cases where such objects exist, their shapes. The method has already been proven effective in restoration activities of wooden Buddhist sculptures.
