Phase–contrast X–ray computed tomography for observing biological soft tissues
Biological soft tissues are almost transparent to hard X rays and therefore cannot be investigated without enhancement with a contrast medium, such as iodine. On the other hand, phase–contrast X–ray… Expand
Blood vessels: depiction at phase-contrast X-ray imaging without contrast agents in the mouse and rat-feasibility study.
The ability of phase-contrast x-ray imaging to depict blood vessels without contrast agents was tested by observing livers of a mouse and a rat with synchrotron x rays. Livers were excised by tying… Expand
Phase-contrast x-ray computed tomography for observing biological specimens and organic materials
A novel three‐dimensional x‐ray imaging method has been developed by combining a phase‐contrast x‐ray imaging technique with x‐ray computed tomography. This phase‐contrast x‐ray computed tomography… Expand

Abstract Synchrotron X-ray imaging systems with phase-contrast and fluorescent techniques have been developed for biomedical researches. Since phase-contrast X-ray imaging with an X-ray… Expand
Phase-Contrast X-Ray Imaging Using an X-Ray Interferometer for Biological Imaging
Since the discovery of X rays, one has benefited from X-ray imaging using its penetrating property. Nowadays, its application expanded into wide variety of fields such as medicine. The contrast… Expand
Human carcinoma: early experience with phase-contrast X-ray CT with synchrotron radiation--comparative specimen study with optical microscopy.
Phase-contrast x-ray computed tomography (CT) indicates the distribution of the refractive index and has potential to reveal the structures inside soft tissues without a contrast agent. With a… Expand
