Need for New Optimisation Strategies in CR and Direct Digital Radiography

摘要: Digital imaging techniques such as Image Intensifier Radiography and Storage Phosphor (Selenium) are replacing conventional film-screen radiography more more. The aim of this development is the extension diagnostic capabilities reduction side effects radiation dose. Conventional digital very different ways imaging. For specific post-processing link between conditions film documentation. Optimisation images includes new possibilities a broad range for variation Especially in fluoroscopy, dose can be reduced significantly by technical features like pulsed fluoroscopy. European guidelines on quality criteria have to applied projection radiography, subtraction Further work should lead definition reference values image quality. This has done first single exposures fluoroscopic mode secondly interventional procedures.
