Elemental contrast full-field imaging using polychromatic X-ray sources
The spatial distribution of individual elements in compound samples has been the subject of extensive interest in many important fields including materials science and engineering, mineral sciences, nanotechnology, medical imaging, archaeology, and so on. However, attempts at quantitative imaging using polychromatic X-ray beams produced from sources available in most small to medium research institutions have been limited.
We are developing an elemental contrast imaging technique using polychromatic X-rays. The technique will be applied to achieve three dimensional elemental contrast imaging of defects in alloys and implants. We will investigate methods in which the techniques developed in the project can be implemented using the broad spectrum X-ray sources.
