Brain tumor imaging using small-angle x-ray scattering tomography

Application of small angle X-ray scattering (SAXS) for differentiation between normal and cancerous breast tissues

ABSTRACT Background: Coherent scattering leads to diffraction effects and especially constructive interferences. Theseinterferences carry some information about the molecular structure of the tissue. As breast cancer isthe most widespread cancer in women, this project evaluated the application of small angleX-ray scattering (SAXS) for differentiation between normal and cancerous breast tissues....

Scanning X-ray imaging with small-angle scattering contrast

An X-ray scanning imaging technique using the integrated intensity of the smallangle X-ray scattering (SAXS) signal is presented. The technique is based on two-dimensional scanning of a thin sample section with an X-ray microbeam, collecting SAXS patterns at every scanning step using a two-dimensional detector. The integrated intensity within pre-defined regions of interest of the SAXS patterns...

Small-angle X-ray scattering characteristics of mouse brain: Planar imaging measurements and tomographic imaging simulations

Small-angle x-ray scattering (SAXS) imaging can differentiate tissue types based on their nanoscale molecular structure. However, characterization of the coherent scattering cross-section profile of relevant tissues is needed to optimally design SAXS imaging techniques for a variety of biomedical applications. Reported measured nervous tissue x-ray scattering cross sections under a synchrotron ...

Ultra-small-angle X-ray Scattering

Magnetic Small Angle X-Ray Scattering

We present first experimental results of the extension of X-ray Magnetic Circular Dichroism (X-MCD) to Small Angle X-ray Scattering (SAXS). The purpose of this study is to determine size distributions and correlations lengths in the nanometer range of magnetic precipitates in granular systems. Magnetic scattering curves obtained with a GdFe system at the Gd La edge are compared with reference m...
