Adaptation of the quality criteria concept to digital radiology

摘要

In recent years conventional film-screen radiography has been more and more replaced by digital techniques like 'Digital Image Intensifier Radiography' and 'Digital Storage Phosphor (Selen) Radiography'. These new digital imaging methods can be used for all areas of radiography except mammography. Digital radiography offers the advantage of additional diagnostic information, digital image format, lower radiation risk to the patient and a favourable cost/benefit relations. With digital techniques, dose can be varied over a wide range without losing diagnostic information.
