Beschreibung
Zusammenfassung:	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.
