自1895年伦琴发现X射线,一个多世纪以来,以X线成像为主导的医学影像设备在医疗机构得到广泛使用。近年来,随着计算机技术和信息技术的进步,放射诊断技术得到了空前的发展,实现了由传统模拟图像信息向数字化图像信息的转变。计算机X线摄影(Computer Radiography,CR)是对常规X射线摄影信息数字化,它将传统的X射线摄影的模拟信息直接转换为数字信息。CR具有灵敏度高、空间分辨率高、信号与真实图
Since 1895, Roentgen discovered X-rays. For more than a century, X-ray imaging-oriented medical imaging equipment has been widely used in medical institutions. In recent years, with advances in computer technology and information technology, radiation diagnostic technology has been an unprecedented development, to achieve a change from the traditional analog image information to digital image information. Computer Radiography (CR) is the digitalization of conventional radiographic information that directly converts the conventional analogue information of X-ray photography into digital information. CR has high sensitivity, high spatial resolution, signal and real map
