| Research Abstract |
For extracted bones (ex vivo), quantitative analysis of the preferred orientation of biological apatite was successfully achieved by using a microbeam X-ray diffraction technique with a transmission optical system. The analytical condition was optimized based on the X-ray absorption coefficient of bone tissue and bone morphology. To expand this technique for in vivo (non-extracted) bone, X-ray absorption profile was taken for the detection of bone totally inside of soft tissues. By combining these techniques, it was possible to detect bone and obtain X-ray diffraction information from bone in vivo. This means the in vivo non-destructive and less-invasive method for analyzing bone quality was established in this study.
