摘要： Photothermographic materials are coated with imaging layers and an antihalation layer between the support and thermally developable imaging layers on one or both sides of the support. Such materials can be arranged in association with one or more phosphor intensifying screens capable of providing emission at a predetermined wavelength in imaging assemblies. These imaging assemblies can be exposed to X-radiation and thereby excited to form a latent image in the photothermographic material that can eventually be used for medical diagnosis. The antihalation layers contain radiation absorbing compounds (such as a UV-radiation absorbing compounds) that absorb radiation at the predetermined wavelength (for example at 300 to 450 nm) and have limited absorption at higher wavelengths.

摘要： A high-speed (over 700) radiographic silver halide film is useful for radiography to provide images with improved contrast and sharpness and reduced fog. The film includes at least one tabular grain silver halide emulsion layer on each side of a film support which grains are dispersed in a hydrophilic polymeric vehicle mixture comprising at least 0.05% of oxidized gelatin, based on the total dry weight of the hydrophilic polymeric vehicle mixture. Where multiple silver halide emulsion layers are disposed on each side of the film support, the emulsion layers closest to the support on each side can include crossover control agents to reduce crossover to less than 15%.

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 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 at a weight ratio of first to second hydrophilic binder of from about 2:1 to about 5:1. 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, 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. These films can be exposed to provide a black-and-white image having a d(γ)/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： A method of mammography imaging includes exposing a patient to a peak voltage greater than 29 kVp. 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 &mgr;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. The film can be exposed to provide a black-and-white image having a d(&ggr;)/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 magenta filter having a density of at least 0.3 to provide improved exposure latitude for use in various exposure conditions and equipment. The magenta filter comprises a transparent support having a hydrophilic layer disposed thereon, which layer includes sufficient dyes or pigments that absorb in the range of from about 500 to about 600 nm. These dyes or pigments are dispersed in a hydrophilic binder to provide the desired density. The magenta filter is laminated to one of the screens with its hydrophilic layer in contact with the screen.

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 having a single silver halide emulsion on each side of a film support and are free of particulate dyes that are conventionally used to control crossover. In addition, the films can be rapidly processed to provide the desired image having visually adaptive contrast, that is the upper scale contrast is at least 1.5 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 radiographic imaging using a wide variety of exposure and processing conditions.
摘要翻译： 当在包括两侧的增强屏幕的射线成像组件中成像时，高性能射线照相胶片呈现视觉上适应的对比度。 这些膜在膜载体的每一侧上具有单一卤化银乳剂，并且不含通常用于控制交叉的颗粒状染料。 此外，可以快速处理胶片以提供具有视觉上自适应对比度的期望图像，即，较高比例对比度至少为下一级对比度的1.5倍。 因此，可以在放射照相图像的较高密度下更好地观察到致密物体，而在较低刻度密度中没有任何不利的感光度变化。 这些膜对于使用各种曝光和加工条件的通用射线照相成像是有用的。
