In several medical centers computed radiography has almost completely replaced the use of conventional screen-film systems for general radiography. The aim of this paper is to explain the basic principles of the four most frequently numerical detectors used in the world, with emphasis on the phosphor plates, which are the most frequently used both in hospitals and by practitioners. The other two systems are based on a receptor with selenium. The fourth uses charged coupled device (CCD) detectors. The most important principles of digital processing are then described with concentration on unsharp mask filtering. In the future computed radiography will replace standard radiology and will create a system in medicine using the power of computers to archive--with more efficiency and less space--patient medical data. The transmission of data to workstations and the processing of this data is the topic of a new field in medicine.
在多个医疗中心，计算机X线摄影几乎已完全取代了传统屏-片系统在普通X线摄影中的应用。本文旨在解释全球最常用的四种数字探测器的基本原理，重点介绍磷光板，它在医院和从业者中使用最为频繁。另外两种系统基于含硒受体。第四种使用电荷耦合器件（CCD）探测器。随后将描述数字处理的最重要原理，重点是锐化掩模滤波。未来，计算机X线摄影将取代传统放射学，并利用计算机的强大功能创建一个医学系统，以更高的效率和更少的空间存储患者医疗数据。数据传输到工作站以及对这些数据的处理是医学新领域的主题。
