Zusammenfassung.
Dieser Artikel gibt einen Überblick über die verschiedenen digitalen Röntgendetektorsysteme für die Projektionsradiographie. Aufbau und Funktionsweisen werden gegenübergestellt und prinzipielle Eigenschaften abgeleitet. Es folgt eine Beschreibung der jeweils zugrunde liegenden Konversions-Mechanismen in der Absorberschicht. Aufbau, Funktionsweise und prinzipielle Eigenschaften von Festkörperdetektoren werden näher erläutert sowie Analogien zur Computer-Tomographie. Einige wichtige System- und Anwendungsaspekte, insbesondere im Vergleich zur konventionellen Radiographie, werden beleuchtet. Den Schluss bildet ein Ausblick auf mögliche Weiterentwicklungen.
Digital detection systems for projection radiography.
This article gives a survey of digital X-ray detection systems for projection radiography. The different principles are compared and some general characteristics are derived. The basic conversion mechanisms in the absorption layers are described. The basic principles of solid state X-ray detectors and their general char-acteristics are elucidated as well as some similarities with detectors for computed tomography. Some important application and system aspects are considered. An outlook on further possible developments in this field is given.
