Synchrotron X-ray Imaging for Materials and Biomedical Sciences
Jung Ho Je
X-ray Imaging Center, Department of Materials Science and Engineering, POSTECH, Korea
Radiology is the oldest and by far the largest field of application of x-rays. In recent years, this domain has been literally revolutionized by the exploitation of the unique characteristics of synchrotron sources. The results are very high quality microradiology and microtomograhy images and movies - taken with a limited x-ray dose – that find a variety of applications in materials science, biology and medical research. In this talk basic theory and selected applications of phase contrast x-ray microscopy to materials and biomedical sciences are reviewed. Furthermore a new strategy of combining phase contrast radiology and diffraction x-ray microscopy is introduced to visualize atomic level defects such as misfit dislocations and micropipes in semiconductor single crystals. Finally phase contrast x-ray imaging in nanometer-resolution (< 30 nm) will be demonstrated.
