常规X线摄片数字化已有16年的历史,主要是由CR实现的。由于价格昂贵,仅仅在一些发达国家的大医院配置该设备。只是近两年来,国内极个别大医院才开始引进,装配DR实现常规X线摄片数字化的医院,仅1999年装配50台。而美国装配33台。因此实现医院常规摄片数字化存在两种设备:DR和CR。医院选择DR还是CR,还是两种都选?DR、CR各有什么优缺点?国际放射界众说纷纭。目前,国内放射界要求实现常规摄片数字化的呼声很高。如果说前几年仅是几家大医院考虑购置CR实现常规X线数字化,而现在90％以上的大医院正考虑或正在着手购置DR和CR,甚至许多中型医院也在考虑或正在购置CR。因此实现常规X线摄片影像数字化,是放射影像发展的必然。为使医院合理配置常规摄片数字化设备,本文论述一些厂商和一些国外较早使用DR、CR医院放射科专家关于DR、
The digitization of conventional X-ray radiographs has a history of 16 years, mainly achieved by CR. Due to the high price, the equipment was only deployed in large hospitals in some developed countries. In the past two years, only a few major domestic hospitals have begun to introduce and install DRs to realize the digitization of conventional radiographs. In 1999, only 50 were equipped. The United States assembles 33 units. Therefore, there are two kinds of equipment for realizing the digitization of the hospital’s conventional radiographs: DR and CR. The hospital chooses DR or CR, or both. DR and CR have their own advantages and disadvantages. There are different opinions in the international radiological community. At present, there is a high demand for the domestic radiological community to achieve the digitization of conventional radiographs. If only a few major hospitals in the previous few years considered purchasing CR to achieve conventional X-ray digitization, now more than 90% of large hospitals are considering or are in the process of purchasing DR and CR. Even many medium-sized hospitals are considering or are purchasing CR. Therefore, the realization of the digitization of conventional X-ray images is inevitable for the development of radiological images. In order to enable the hospital to properly configure conventional digital imaging equipment, this article discusses the use of DR and CR hospital radiology experts by some manufacturers and some foreign countries on DR.
