New Approach may Lead to Improvements in Medical Diagnostic X-Rays

Scintillators are materials that emit light when bombarded with high-energy particles or X-rays. In medical or dental X-ray systems, they convert incoming X-ray radiation into visible light that can then be captured using film or photosensors. They're also used for night-vision systems and for research, such as in particle detectors or electron microscopes.
