During the past two decades, digital radiography has supplanted screen-film radiography in many radiology departments. Today, manufacturers provide a variety of digital imaging solutions based on various detector and readout technologies. Digital detectors allow implementation of a fully digital picture archiving and communication system, in which images are stored digitally and are available anytime. Image distribution in hospitals can now be achieved electronically by means of web-based technology with no risk of losing images. Other advantages of digital radiography include higher patient throughput, increased dose efficiency, and the greater dynamic range of digital detectors with possible reduction of radiation exposure to the patient. The future of radiography will be digital, and it behooves radiologists to be familiar with the technical principles, image quality criteria, and radiation exposure issues associated with the various digital radiography systems that are currently available.
在过去二十年中，数字放射成像已在许多放射科取代了屏-片放射成像。如今，制造商基于各种探测器和读出技术提供了多种数字成像解决方案。数字探测器使得完全数字化的图像存档与通信系统得以实现，在此系统中，图像以数字方式存储且随时可用。医院内的图像分发现在可通过基于网络的技术以电子方式实现，不存在图像丢失的风险。数字放射成像的其他优势包括更高的患者通量、更高的剂量效率，以及数字探测器更大的动态范围，这有可能减少患者所受的辐射剂量。放射成像的未来将是数字化的，放射科医生理应熟悉当前可用的各种数字放射成像系统所涉及的技术原理、图像质量标准以及辐射剂量问题。
