    摘要: A radiographic X-ray film comprising a polymer support. One or more silver halide emulsion layers are coated on each side of the support. A blue dye is contained within at least one of the polymer support or in an adjacent hydrophilic layer in a sufficient amount to result in a CIELAB measurement of L* less than or equal to 80 and b* less than or equal to −25. This configuration provides, after imaging and development, radiographic images having desirable visual contrast, image tone, b*, and image quality.

    摘要: A radiographic imaging assembly has first and second radiographic silver halide films in association with two fluorescent intensifying screens. Between one set of screen and film is a neutral density filter having a density of at least 0.3 to provide with improved exposure latitude for use in various exposure conditions and equipment. The neutral density filter comprises a transparent support having a hydrophilic neutral density filter layer disposed thereon, which layer includes sufficient silver metal, colloidal carbon, or exposed and processed silver halide in a hydrophilic binder to provide the desired density. The neutral density filter is laminated to one of the screens with its hydrophilic layer in contact with the screen.

    摘要: High performance, very high contrast radiographic films exhibit visually adaptive contrast when imaged in radiographic imaging assemblies comprising intensifying screens. These films having at least two tabular silver halide emulsions on each side of a film support, and the emulsion closest to the film support on each side includes chemistry to control crossover and a rhodium dopant and has higher photographic speeds than the other emulsions. In addition, the films can be rapidly processed to provide images having visually adaptive contrast wherein the upper scale contrast is at least 1.7 times the lower scale contrast. These films are particularly useful for orthopedic imaging.

    摘要: A direct radiographic film is usefull for dental care. The film contains lower than normal amounts of silver 30-45 mg/dm2) and gelatino-vehicle 15-30 mg/dm2) in each silver halide emulsion unit but retains the ability to provide desired sensitometric results. The film comprises predominantly non-spectrally sensitized silver bromide tabular grains.

    摘要: High performance radiographic films exhibit visually adaptive contrast when imaged in radiographic imaging assemblies comprising an intensifying screen on both sides. These films have at least two silver halide emulsions (preferably tabular grains) on each side of a film support, and the emulsion closest to the film support on each side includes chemistry to control crossover. In addition, the films can be rapidly processed to provide the desired image whereby the upper scale contrast is at least 1.2 times the lower scale contrast. Thus, dense objects can be better seen at the higher densities of the radiographic image without any adverse sensitometric changes in the lower scale densities. These films have greater dynamic range that allows them to be scanned and digitized to correct for under- or over-exposure.
