Patent ID: 6967071

Claim:
A radiographic imaging assembly that has a system speed of at least 700 and comprises: A) a symmetric radiographic silver halide film having a film speed of at least 400 and comprising a support that has first and second major surfaces, said radiographic silver halide film having disposed on said first major support surface, one or more hydrophilic colloid layers including a first silver halide emulsion layer, and having on said second major support surface, one or more hydrophilic colloid layers including a second silver halide emulsion layer, and B) a fluorescent intensifying screen arranged on each side of said radiographic silver halide film, the pair of screens having a screen speed of at least 400 and said screens having an average screen sharpness measurement (SSM) value greater than reference Curve A of FIG. 4 , and each screen comprising an inorganic phosphor capable of absorbing X-rays and emitting electromagnetic radiation having a wavelength greater than 300 nm, said inorganic phosphor being coated in admixture with a polymeric binder in a phosphor layer on a support.
