Description
An x-ray image converter for converting x-rays to visible light after passage through a photographed object in order to produce improved colored radiographs on an associated color photographic film attributable to localized color shift in the photographic film medium. The desired color shift produced by the x-ray image converter is achieved with use of a phosphor material which exhibits differential absorption of the x-radiation in the 35-50 kev region due to K alpha edge effects. In the conversion of xrays to visible light in the desired manner, the new phosphor combination is useful in x-ray image intensifier tubes, in fluoroscopic screens, in radiographic intensifier screens, and other x-ray image converter devices
