Abstract
An x-ray intensifying screen is provided in which high resolution is obtained by minimizing back reflections within a luminous layer, which reflections are generally laterally directed such that light emitted from a given area within the layer is diffused. The screen includes an anti-reflecting surface at the back side of the luminous layer in which a plurality of randomly positioned leaflets extend from the surface. The layer is typically formed of a microstructured layer of boehmite, a hydrated aluminum oxide.
