| Research Abstract |
In this study, X-ray imaging was tested using parallel X-ray beam from undulateor light source of the SPring-8. Projection images were measured at X-ray energies of 8 and 28.8 keV with X-ray image detector that is placed atr 5-5.6m downstream from specimen. Transmission image of a test sample shows good agrrement with ray-trace simulation. The intensity profile can be explained by refraction of X-rays. Detection of Transmitted beam is also measured by using fine X-0ray beam collimated by a slit. The deflection angel of X-rays through the sample is around a few microobservation of soft tissues of biological specimen. The results also well agrees with sample calculation based on geometrical optics. This technique is applied to observation of soft tissues of biological specimen. The result for lung image of nude mouse is preseted, and difference between contact image (absorption-contrast) and refraction contrast image is discussed.
This is a promising new technique for the diagnosis in the human lung with a low dose.
