Digital radiography is a generally accepted term comprising all x-ray image systems producing a projected image which resembles the conventional x-ray film image, and which are linked to any type of digital image processing. Fundamental criteria of differentiation are based on the production and detection method of the x-ray image. Various systems are employed, viz. the single-detector, line-detector or fanbeam detector and the area-beam or area-detector image converters, which differ from one another mainly in the manner of conversion of the radiation produced by the x-ray tube. The article also deals with the pros and cons of the various principles, the multitude of systems employed, and the varying frequency of their use in x-ray diagnosis work.
数字放射摄影是一个被广泛接受的术语，涵盖了所有产生类似传统X线胶片图像的投影图像且与任何类型数字图像处理相连接的X线成像系统。区分的基本标准基于X线图像的产生和检测方法。采用了各种系统，即单探测器、线探测器或扇形束探测器以及面束或面探测器图像转换器，它们彼此之间的主要区别在于X线管产生的辐射的转换方式。本文还讨论了各种原理的优缺点、所采用系统的多样性以及它们在X线诊断工作中的不同使用频率。
