Outline of Final Research Achievements

We are developing a non-destructive portable inspection machine using the ultra-compact X-ray source developed by Dr. Suzuki for a standing tree. We conducted a experiment for green wood of 4 species (Japanese cedar, Japanese cypress, Japanese black pine, Japanese larch) with a prototype machine. We found that it is possible to detect heartwood, sapwood, growth ring and knots area from the obtained CT images. This means that the developed portable inspection machine would have applicability to non-destruct wood quality assessment for standing tree. We showed that the developed portable inspection machine do not have applicability to research on pine wilt disease presently because it is difficult to detect the xylem cavitation area in sapwood from CT images due to lower resolution. There is a need for further improvement of the machine.
