    摘要： A radiographic imaging assembly has a first radiographic silver halide film that provides high contrast images in association with a second radiographic silver halide film that provides lower contrast images. The combination of two films, with or without one or more fluorescent intensifying screens, provides images with excellent contrast and improved exposure latitude for use in various exposure conditions and equipment. The ratio of contrast of images provided by the first and second radiographic silver halide films is at least 1.25.

    摘要： A method of mammography imaging includes exposing a patient to a peak voltage greater than 29 kVp using X-radiation generating equipment comprising rhodium or tungsten anodes. The film used in this method 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 about 540 to about 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. The cubic silver halide grains comprise from about 1 to about 20 mol % chloride and from about 0.25 to about 1.5 mol % iodide, both based on total silver in the cubic grain emulsion layer, which cubic silver halide grains have an average ECD of from about 0.65 to about 0.8 μm. Moreover, the cubic silver halide grains are doped with a hexacoordination complex compound within part or all of the innermost 95% of the grains. The film can be exposed to provide a black-and-white image having a d(γ)/d(log E) value greater than 5.

    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： Radiographic films containing cubic grain, high silver chloride emulsions can be used in radiographic imaging assemblies comprising intensifying screens for therapy portal localization imaging. The average silver halide grain size is from about 0.1 to about 0.18 &mgr;m and the silver halide is free of silver halide dopant compounds. These films provide excellent contrast with improved exposure latitude (at least 4:1 when measured at a gamma value of 1.5) for use in various exposure conditions and equipment.
