Abstract:
A radiographic imaging assembly comprising the following components arranged in association, in order:(a) a first fluorescent intensifying screen, (b) a first radiographic silver halide film, (c) a second radiographic silver halide film, and (d) a second fluorescent intensifying screen, wherein said first and second fluorescent intensifying screens differing in photographic speed by at least 0.1 logE, and said first and second radiographic silver halide films being the same or different, and each comprising a support having first and second major surfaces and is capable of transmitting X-radiation, said first and second radiographic silver halide films having disposed on said first major support surface, one or more hydrophilic colloid layers including at least one silver halide emulsion layer, and on said second major support surface, one or more hydrophilic colloid layers including at least one silver halide emulsion layer, and each of the silver halide emulsion layers comprising silver halide cubic grains that have the same or different composition in each silver halide emulsion layer, and all hydrophilic layers of said first and second radiographic silver halide films being fully forehardened and wet processing solution permeable for image formation within 45 seconds.
