Minimal crossover radiographic elements and assemblies adapted for flesh and bone imaging

An imaging assembly intended to produce relatively sharp images of bone and useful images of surrounding tissue when exposed to X-radiation comprising:

• a front intensifying screen,
• a back intensifying screen, and a radiographic element comprised of
• a transparent film support,
• front and back silver halide emulsion layer units coated on opposite sides of the film support with said front and back emulsion layer units located adjacent to the front and back intensifying screens, respectively,
• means for reducing to less than 10 percent crossover of electromagnetic radiation of wavelengths longer than 300 nm capable of forming a latent image in the silver halide emulsion layer units, said crossover reducing means being decolorized in less than 30 seconds during processing of said emulsion layer units,
• wherein,
• at a density of 1.0,
• said back silver halide emulsion layer unit exhibits a speed exceeding by from 0.3 to 1.0 log E that of said front silver halide emulsion layer unit,
• said back silver halide emulsion layer unit exhibits a contrast in the range of from 2.0 to 4.0, and
• said front silver halide emulsion layer unit exhibits a contrast in the range of from 0.5 to 1.7
• the speed and contrast of the back silver halide emulsion layer unit being determined with the back silver halide emulsion layer unit replacing the front silver halide emulsion layer unit to provide an arrangement with identical silver halide emulsion layer units present on both sides of the transparent support and
• the speed and contrast of the front silver halide emulsion layer unit being determined with the front silver halide emulsion layer unit replacing the back silver halide emulsion layer unit to provide an arrangement with identical silver halide emulsion layer units present on both sides of the transparent support.
