Abstract:
1. A method of imaging for mammography comprising exposing a patient to X-radiation at a peak voltage greater than 28 kVp using an X-radiation generating device comprising rhodium or tungsten anodes, and providing a black-and-white image of the exposed patient using an imaging assembly comprising: A) a radiographic silver halide film that comprises a support having first and second major surfaces and that is capable of transmitting X-radiation, said radiographic silver halide film having disposed on said first major support surface, one or more hydrophilic colloid layers including at least one cubic grain silver halide emulsion layer, and having disposed on said second major support surface, one or more hydrophilic colloid layers including at least one tabular grain silver halide emulsion layer, wherein said film can be exposed to provide a black-and-white image having a d(γ)/d(log E) value greater than 5, and B) a fluorescent intensifying screen that comprises an inorganic phosphor capable of absorbing X-rays and emitting electromagnetic radiation having a wavelength greater than 300 nm.
