Abstract
An improved X-ray intensifying screen comprising phosphor crystals having an effective amount of a light scattering particulate material, e.g., barium sulfate, strontium sulfate, calcium sulfate, titanium dioxide or magnesium oxide, adhered thereto is described. This screen will give high speed and yield an image with increased sharpness when exposed with a single-side coated medical X-ray film element, compared to one made without the particulate material.
