    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.

    摘要： A radiographic element is disclosed capable of producing a maximum density of at least 3.0 when imagewise exposed and processed in less than 45 seconds. The element includes magenta dye or dyes, including a dye for spectrally sensitizing radiation-sensitive silver halide grains, that leave a residual density at 505 nm of greater than 0.1 when the element is processed. Transmission of red light through the radiographic element when imagewise exposed and processed to produce a viewable image is reduced by the incorporation in at least one of the hydrophilic colloid layers of at least one ionic linear condensation polymer containing a cyan phthalocyanine dye.
