八十年代末九十年代初,日、美及西方国家,先后推出称为Computed Radiography(简称CR)的具有计算机图像处理功能的新型数字X光影像仪。它一出现,立即在世界各地,特别是在医疗界,掀起了一股“CR”热,这是因为其清晰的X光图像可反复使用上千次的X光影像权,灵活方便的计算机图像处理是老式X光机不能比拟的,因而备受人们的青睐。不仅如此,其相当可观的经济效益,更是令人向往。日本的CR仪,一台套售价高达80～100万美元,由此可见一斑。
In the late 1980s, Japan, the United States and Western countries, a new digital X-ray imager with computer image processing called Computed Radiography (CR) was successively launched. As soon as it appeared, a “CR fever” was set off all over the world, especially in the medical community, because of its clear X-ray images that can be reused thousands of times X-ray imaging rights, flexible and convenient computer images The treatment is incomparable with the old X-ray machine, which has been favored by people. Not only that, its considerable economic benefits, but also desirable. Japan’s CR meter, a set of prices up to 80 to 1 million US dollars, as can be seen.
