An radiographic imaging system for making a radiograph by a radiography apparatus using a photographic combination of a silver halide photographic material having light sensitive layers on both sides of the support and an intensifying screen is disclosed, wherein the photographic material exhibits a cross-over of not more than 15%, a specified point gamma value within the specified density range on the characteristic curve when the photographic combination is exposed to X-ray, and wherein the radiography apparatus conducts making a radiograph under the condition that a distance between a focal point of an X-ray tube and the photographic combination is 1.0 to 3.0 m and a distance between an object and the photographic combination is 0.2 to 1.5 m.
本发明公开了一种射线成像系统,该系统用于通过射线照相装置制作射线照片,射线照相装置使用的照相组合包括在支撑物两侧具有感光层的卤化银照相材料和增感屏,其中,当照相组合暴露于 X 射线时,照相材料显示出不超过 15%的交叉,在特性曲线上的指定密度范围内显示出指定点伽马值,并且射线照相装置在 X 射线管的焦点与照相组合之间的距离为 1.0 至 3.0 米,物体与摄影组合之间的距离为 0.2 至 1.5 米。
