Asymmetric radiographic film for mammography and method of processing |
摘要 |
An asymmetric radiographic silver halide film has two cubic grain silver halide emulsion layers on the frontside and a tabular grain silver halide emulsion layer on the backside. The cubic grain silver halide emulsion layer closer to the support also includes a crossover control agent to reduce crossover to the backside to less than 10% and is thinner than the outermost cubic grain silver halide emulsion layer. The backside of the support also includes an antihalation layer. These films are useful for imaging soft tissue as in mammography.
