Research Abstract |
We experimentally studied on diffraction-enhanced imaging (DEI), which is a kind of X-ray phase-contrast imaging, with a magnification effect based on a cone-like beam from the parametric X-ray (PXR) source at LEBRA, Nihon University. As a result of the experiment, a phase-gradient image was actually obtained with a magnification power of 1.21. In order to advance the DEI method employing PXR, we successfully demonstrated novel imaging based on small-angle X-ray scattering (SAXS) due to sample materials. In the imaging experiment, styrene foam was used for the sample material irradiated with 25.5-keV X-rays. As the result, relatively strong image-contrast was observed at the styrene-foam region, in which the X-ray attenuation is negligible. Thus, we concluded that the SAXS image by this method reflects different information from that of ordinary X-ray images.
