Abstract
A radiographic imaging assembly has first and second radiographic silver halide films in association with two fluorescent intensifying screens. Between one set of screen and film is a magenta filter having a density of at least 0.3 to provide improved exposure latitude for use in various exposure conditions and equipment. The magenta filter comprises a transparent support having a hydrophilic layer disposed thereon, which layer includes sufficient dyes or pigments that absorb in the range of from about 500 to about 600 nm. These dyes or pigments are dispersed in a hydrophilic binder to provide the desired density. The magenta filter is laminated to one of the screens with its hydrophilic layer in contact with the screen.
