ABSTRACT:
X-ray image converters using rare earth oxyhalide phosphors activated with terbium and/or thulium ion are described exhibiting improved brightness. Novel reflector means are provided in said x-ray image converter devices which reflect UV radiation incident thereupon back through the phosphor layer to associated readout or recording means sensitive to this wavelength radiation. A multi layer x-ray screen construction utilizing said improved reflector means is also described providing improved image sharpness while further reducing the crossover problem because more reflected UV radiation is being transmitted to an associated photographic film.
