Abstract: A wide latitude, high resolution radiographic system having a relative speed of at least 150 and a contrast transfer function of at least 0.30 when measured at 6 line pairs per millimeter, comprises at least one X-ray intensifying screen in operative association with a photosensitive silver halide element having a maximum contrast of less than or equal to 3.0 produces superior images, particularly chest images over a wide range of exposures, without the decrease in image quality or contrast normally seen in wide latitude systems.

Abstract: A high resolution radiography system is presented utilizing a an intensifying screen incorporating a UV emitting phosphor. The photographic element exhibits enhanced sensitivity to the emission of the phosphor and further comprises at least one compound selected from the group comprising: ##STR1## wherein R.sub.1 =substituted or unsubstituted aromatic ring; R.sub.2 =H, substituted or unsubstituted alkyl or substituted or unsubstituted aryl; R.sub.3 =an alkyl group, an aryl group, a COOR group wherein R is hydrogen, alkyl, aryl or an alkali metal cation, HNR4+ wherein R.sub.4 is alkyl, substituted alkyl or alkyaryl.
