Abstract
A composite phosphor screen for converting radiation, such as X-rays, into visible light. The screen includes a planar surface, which can be formed from glass, silicon or metal, which has etched therein a multiplicity of closely spaced microchannels having diameters of the order of 10 microns or less. Deposited within each of the microchannels is a multiplicity of phosphors which emit light when acted upon by radiation. A photomultiplier, which may be microchannel based, is integrated with the X-ray detector so as to provide an enhanced output for use with low level X-ray of for cine or fluoroscopy applications. The walls of the microchannels and/or the substrate surfaces include dielectric stack based light reflective coatings.
