AXS Image Ondition of Beam Is Small Angle X-Ray Scattering Imaging of Soft Tissue by Using Laue Diffraction Optical System
2018
We
performed a feasibility study of small angle X-ray scattering imaging under the condition of X-ray bright field imaging by Laue crystal
diffraction optics of X-ray dark-field imaging that works as an angular
analysis. Collagen in chicken tibia containing abundant soft fibrous tissue was
chosen as a specimen. In traditional small angle X-ray
scattering optical system, we can derive the structure
information of sample by calculating q value
which is available from a scattering pattern. Thus it is usually necessary to
conduct a 2D scan in order to obtain scattering image. In this paper it is
described by a
method by which not only small angle X-ray scattering imaging is available
directly but also bright-field
imaging and dark-field
imaging can be obtained at the same time. As the first step, the
feasibility of the imaging method should be confirmed by taking pictures of the
samples with known periodic length. The preliminary test showed that the collgan’s
lattice spacing d is
65.1 nm that was also taken photos by scanning electron microscopy. By rotating
Laue angular analyzer by 112 arcseconds small angle X-ray scattering image
appeared in bright-field.
