Abstract

We present several examples of the applications of a novel microradiology approach based on unmonochromatized synchrotron x-rays. The approach - mostly implemented on the ICPCIR (International Consortium on Phase Contrast Imaging and Radiology) Beamline at the 7B2 Pohang Light Source in Korea, Phase Contrast Imaging (PCI) beamline of Singapore Synchrotron Light and Source and at the B1 wavelength shifter beamline in NSSRC Hsinchu, Taiwan - allows the real-time analysis of a variety of phenomena on the micron and submicron scale. The practical examples concern materials science, industrial technology, medicine, the life sciences and other areas.

Phase-contrast imaging

Phase-contrast imaging is a method of that has a range of different applications. It measures differences in the refractive index of different materials to differentiate between structures under analysis. In conventional light microscopy, phase contrast can be employed to distinguish between structures of similar transparency, and to examine crystals on the basis of their double refraction. This has uses in biological, medical and geological science.

Phase-contrast X-ray imaging

Phase-contrast X-ray imaging or phase-sensitive X-ray imaging is a general term for different technical methods that use information concerning changes in the phase of an X-ray beam that passes through an object in order to create its images. Standard X-ray imaging techniques like radiography or computed tomography (CT) rely on a decrease of the X-ray beam's intensity (attenuation) when traversing the sample, which can be measured directly with the assistance of an X-ray detector.

Phase-contrast microscopy

NOTOC Phase-contrast microscopy (PCM) is an optical microscopy technique that converts phase shifts in light passing through a transparent specimen to brightness changes in the image. Phase shifts themselves are invisible, but become visible when shown as brightness variations. When light waves travel through a medium other than a vacuum, interaction with the medium causes the wave amplitude and phase to change in a manner dependent on properties of the medium.
