    摘要: Disclosed is a color silver halide photographic element comprising a support bearing: (1) a light sensitive silver halide emulsion layer; (2) a nitrogen heterocycle with a minimum of three heteroatoms that does not react with oxidized developer, does not contain free thiol substituents, and has a ClogP sufficient to increase the photographic speed of said element compared to the same element without the compound, said heterocycle compound located either in said light sensitive layer or in a layer adjacent to it; and (3) a light reflecting silver halide material; provided that the heterocycle compound and the light reflecting material are located either (a) in different layers of the element located close enough to each other so that a super-additive speed increase is realized or (b) in the same light sensitive layer. The invention provides improved light sensitivity.

    摘要: An x-ray detector, detection assembly, and method of using the detector and detection assembly. The detector is used with an x-ray source and has a converter including a mass of prompt emitting radiographic phosphor particles and a photoconductive binder. The mass of particles is dispersed and embedded in the binder. The phosphor absorbs x-rays emitted by the source and emits longer wavelength actinic radiation responsive to the x-rays. The photoconductive binder absorbs the actinic radiation and produces electron-hole pairs responsive to the actinic radiation.
