研究の背景 Background


The techniques for utilizing X-ray phase information or coherence have been developed remarkably, and the field of Xray imaging is progressing well. While conventional X-ray imaging methods relying on absorption contrast are widely used in medicine and non-destructive testing, X-ray phase-contrast method allows us to observe materials consisting of low-Z elements, such as polymers and biological soft tissues, which cannot be depicted with the conventional methods.

研究の目標 Outcome


X-ray optics is extensively studied to develop advanced imaging methods, such as X-ray microscopy or tomography utilizing phase information. Phase imaging with other quantum beams, such as neutron beam, is also studied. Through these activities, contribution to the modern society with increasing attention to health, safe, and secure by developing apparatus for medical diagnosis and non-destructive testing in collaboration with industry.
