Phase contrast X - ray imaging
In the last decade X-ray imaging based on phase contrast greatly advanced thanks to the use of unmonochromatic synchrotron hard X-rays. The recent advances are going beyond microradiology and microtomography to reach nanometre scale. This paper reviews basic theory and selected applications to biomedical and materials sciences. The forthcoming improvements in phase contrast X-ray imaging will l...
متن کاملPhase-Contrast X-ray imaging
Virtually all X-rays imaging in a medical or biological context is performed by measuring differences in the attenuation of X-rays by the tissues. The material properties are inferred from the differences in the number of photons detected at the end of defined paths in the sample. Naturally then this form of X-ray imaging concentrates almost entirely on the particle side of X-ray behaviour. The...
متن کاملDevelopment of an X-Ray Interferometer for High-Resolution Phase-Contrast X-Ray Imaging
An X-ray interferometer for high-resolution phase-contrast X-ray imaging was developed by thinning the central part of the analyzer crystal of a triple Laue-case (LLL) X-ray interferometer. The interferometer was tested at beamline 47XU at the SPring-8, and the improvement of the resolution of interference patterns was successfully observed for a plastic sphere of 1 mm diameter.
متن کاملPropagation based phase contrast x-ray imaging of Caenorhabditis elegans
Introduction: Imaging of multicellular organisms with nano-scale resolution is one of the challenges of modern life sciences. To solve biological problems, often the combined information of several microscopy techniques is necessary. While confocal fluorescence microscopy and optical super-resolution fluorescence can detect the distribution of markers in live cells, electron microscopy (EM) off...
متن کاملThree-dimensional phase-contrast X-ray microtomography with scanning–imaging X-ray microscope optics
A three-dimensional (3D) X-ray tomographic micro-imaging system has been developed. The optical system is based on a scanning-imaging X-ray microscope (SIXM) optics, which is a hybrid system consisting of a scanning microscope optics with a one-dimensional (1D) focusing (line-focusing) device and an imaging microscope optics with a 1D objective. In the SIXM system, each 1D dataset of a two-dime...
