Rapidly processable and directly viewable radiographic film with visually adaptive contrast |
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. |
