ASSEMBLY OF SILVER HALIDE PHOTOGRAPHIC SENSITIVE MATERIAL AND RADIATION-SENSITIZING SCREEN AND RADIATION SENSITIZING SCREEN AND SILVER HALIDE PHOTOGRAPHIC SENSITIVE MATERIAL

摘要

PURPOSE: To provide the novel assembly of a silver halide photographic sensitive material and radiation-sensitizing screens which has the sensitivity sufficient for practicable use and forms X-ray images having improved image quality. ;CONSTITUTION: The radiation image-formable assembly consisting of the silver halide photographic sensitive material and two sheets of the radiation-sensitizing screens respectively disposed on both sides thereof exhibit 25% or more absorption quantity to X-rays of 80KVp X-ray energy and has a high space frequency of a contrast transmission function. The silver halide photographic sensitive material is provided with silver halide photographic sensitive layer respectively on both sides of a base. These photosensitive layers have the sensitivity that the exposure necessary for the density obtd. at the photosensitive layers by exposing the photosensitive layers with the monochromatic light of the same wavelength as the wavelength of the main light emission peak of the sensitizing screens, subjecting the layers to development processing, peeling the photosensitive layers on the side opposite from the exposed surface and measuring the layers to attain the value adding 0.5 to the min. density attains 0.010 to 0.035 lux second.;COPYRIGHT: (C)1994,JPO&Japio
