Synchrotron Radiation and Its Applications in Biomedical and Healthcare X-Ray Imaging

Abstract

This article first introduces the generation principles of synchrotron radiation (SR), its main performance characteristics, and major synchrotron facilities in Japan. It then provides an overview of various SR-based imaging techniques utilizing synchrotron radiation, discussed from the three perspectives of spatial, temporal, and density resolution. Furthermore, the article presents imaging studies conducted by the author, including an outline and measurement examples of the cryo-micro X-ray CT system operating at beamline BL07 of the Kyushu Synchrotron Light Research Center (SAGA-LS), and the principle, instrumentation, and biomedical imaging examples obtained using a two-crystal X-ray interferometric imaging system installed at beamline BL-14C of the Photon Factory (KEK PF).
