    摘要: 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. The walls of the microchannels and/or the substrate surfaces include light reflective coatings so as to reflect the light emitted by the phosphors to the light collecting devices, such as film or an electronic detector. The coatings can be either radiation transparent or filtering/attenuating depending on the particular application.

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.
