Giving X-ray vision a sense of direction

Phys · · 635 words · By Torsten Fischer
Scientific Innovation Biomedical Applications Nanoscale Imaging

An international research team led by the Helmholtz Center Hereon has developed a new X-ray imaging method that allows for the determination of the spatial orientation of nanostructures. The technique, which utilizes directional dark-field imaging, has been tested on nanoporous silicon and human tooth enamel to provide insights into material stability and pathological changes.
