摘要： An imaging assembly includes a blue-sensitive, radiographic silver halide film comprises a silver halide emulsion layer comprising predominantly tabular silver halide grains that have an aspect ratio of at least 15, a grain thickness of at least 0.1 mu m, and comprise at least 90 mol % bromide and up to 4 mol % iodide, based on total silver halide. The tabular silver halide grains are dispersed in a hydrophilic polymeric vehicle mixture comprising at least 0.5% of oxidized gelatin. The film is used in combination with one or more intensifying screens that absorb X-radiation and emit radiation having a wavelength of from 300 to 500 nm. In many embodiments, the intensifying screens include a "blue-light" emitting alkaline earth fluorohalide phosphor dispersed in a binder on a support.

摘要： A radiographic silver halide film comprises a cubic grain silver halide emulsion layer on one side of the support and a tabular grain silver halide emulsion layer on the other side. The cubic grain silver halide emulsion layer comprises a combination of first and second spectral sensitizing dyes that provides a combined maximum J-aggregate absorption on the cubic silver halide grains of from 540 to 560 nm. The first spectral sensitizing dye is an anionic benzimidazole-benzoxazole carbocyanine, the second spectral sensitizing dye is an anionic oxycarbocyanine. The cubic grain silver halide emulsion layer also includes a mixture of gelatin or a gelatin derivative and a second hydrophilic binder other than gelatin or a gelatin derivative at a weight ratio of first to second hydrophilic binder of from 2:1 to 5: 1. The cubic silver halide grains comprise from 1 to 20 mol % chloride and from 0.25 to 1.5 mol % iodide, which cubic silver halide grains have an average ECD of from 0.65 to 0.8 mu m. Moreover, the cubic silver halide grains are doped with a hexacoordination complex compound within part or all of the innermost 95% of the grains. These films can be exposed to provide a black-and-white image having a d( gamma )/d(log E) value greater than 5 and are particularly useful when imaged using X-radiation generating devices comprising rhodium or tungsten anodes.

摘要： High performance, high contrast radiographic films exhibit visually adaptive contrast when imaged in radiographic imaging assemblies comprising an intensifying screen on both sides. These films having at least two 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 has higher photographic speeds than the other emulsions. In addition, the films can be rapidly processed to provide the desired image having visually adaptive contrast, i.e. the upper scale contrast is at least 1.7 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 are useful for general purpose, high contrast radiographic imaging.
