X线机是医学上诊断疾病的常用主要设备之一,已有80余年的历史。自1952年国际上出现了第一台影象增强器后,X线设备发展更快,目前已普遍地采用影象增强电视系统,提高了分辨率和清晰度,减少病员受照剂量,并可明室操作及远距离控制,改善了防护条件。西德西门子厂生产的X线机在使用影象增强器作电视透视时,还可以随病人肥瘦自动调节亮度和放大作更详尽的透视。目前国际上影象增强管都用碘化铯代替硫化锌镉为输入屏荧光材料,进一步提高了分辨
X-ray machine is one of the commonly used major equipment for diagnosing diseases in medicine, and has more than 80 years of history. Since the appearance of the first image intensifier in the world in 1952, the development of X-ray equipment has been accelerated. At present, image-enhanced television systems have been widely used to improve the resolution and sharpness and reduce the doses to patients Ming room operation and long-distance control, improved protection conditions. West Germany Siemens plant production of X-ray machines in the use of image intensifier for television perspective, but also with the patient fat automatically adjust the brightness and zoom in for more detailed perspective. At present, the international image enhancement tubes use cesium iodide instead of zinc sulfide cadmium as the input screen fluorescent material, to further improve the resolution
