Stigmatic X-ray imaging using a single spherical Laue crystal
We propose a crystal configuration using a single Laue spherical crystal for imaging applications. A crystal in Laue geometry set to focus a divergent beam in the meridional (diffraction) plane, but does not focus in the sagittal plane. A transmission object placed in the beam is imaged with different horizontal and vertical aspect ratio, but it is possible to find a configuration with similar ...
متن کاملDevelopment of a bent Laue beam-expanding double-crystal monochromator for biomedical X-ray imaging
The Biomedical Imaging and Therapy (BMIT) beamline at the Canadian Light Source has produced some excellent biological imaging data. However, the disadvantage of a small vertical beam limits its usability in some applications. Micro-computed tomography (micro-CT) imaging requires multiple scans to produce a full projection, and certain dynamic imaging experiments are not possible. A larger vert...
متن کاملNoise and analyzer-crystal angular position analysis for analyzer-based phase-contrast imaging.
The analyzer-based phase-contrast x-ray imaging (ABI) method is emerging as a potential alternative to conventional radiography. Like many of the modern imaging techniques, ABI is a computed imaging method (meaning that images are calculated from raw data). ABI can simultaneously generate a number of planar parametric images containing information about absorption, refraction, and scattering pr...
متن کاملCharacterization of a bent Laue double-crystal beam-expanding monochromator
A bent Laue double-crystal monochromator system has been designed for vertically expanding the X-ray beam at the Canadian Light Source's BioMedical Imaging and Therapy beamlines. Expansion by a factor of 12 has been achieved without deteriorating the transverse coherence of the beam, allowing phase-based imaging techniques to be performed with high flux and a large field of view. However, preli...
متن کاملStatic Laue diffraction studies on acetylcholinesterase.
Acetylcholinesterase (AChE) is one of nature's fastest enzymes, despite the fact that its three-dimensional structure reveals its active site to be deeply sequestered within the molecule. This raises questions with respect to traffic of substrate to, and products from, the active site, which may be investigated by time-resolved crystallography. In order to address one aspect of the feasibility ...
