High contrast visually adaptive radiographic film and imaging assembly for orthopedic imaging

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.
