X-ray phase contrast imaging

Technology Description

A novel non-destructive testing method based on microfabricated diffraction gratings using either high brilliance X-rays from a synchrotron source or conventional X-rays from an X-ray tube allows the direct imaging of the phase contrast in the X-ray beam induced by the object under investigation.

Applications / use-cases:

Medical investigations, particularly cancer diagnosis.
Non destructive materials investigations and testing.
Inspection systems for production.
Safety inspection of e.g. luggage at airports.

Advantages over current alternatives:

Higher sensitivity over classical absorption contrast methods.
Better selectivity between different materials
