直接数字化X线摄影技术

Direct Digital Radiography(DDR)

数字X线摄影是指利用电子计算机数字化潜能与常规X线摄影及装置相组合,将其X线信息转换成数字形式,经后处理成像的方法。直接数字X线摄影是在上述基础上省略信息采集中的中间传递环节,具有成像快,影像质量高的特征。本文对直接数字化成像技术的特点、构造、工作原理、影像质量等进行概述。

Digital radiography （DR） which combines the digital potentials of computer and routine radiography as well as its devices transferred the X-ray information into digitals for imaging. DDR was created on the basis of DR. It omits the intermediate transfer tache and has the merits of rapid imaging and high quality. We reviewed the characteristics, structure,working mechanism and image quality of DDR.
