ABSTRACT:
A radiographic imaging assembly comprises a symmetric radiographic silver halide film has an overall system speed of at least 200 but less than 800 to provide images with improved contrast and sharpness and reduced fog. The imaging assembly includes a symmetric radiographic silver halide film having a speed of at least 700 that includes two silver halide emulsions on both sides of the support that comprise tabular silver halide grains. The emulsions closer to the support comprise a suitable crossover control agent. The imaging assembly also includes a pair of phosphor intensifying screens that have a screen sharpness measurement (SSM) greater than reference Curve A of FIG.4. The screens can have a support that includes a reflective substrate comprising a continuous polyester phase and microvoids containing inorganic particles dispersed within the polyester phase.
