A Learning Content Management System developed locally was used as template, providing a complete web site based on systematic and quick navigation, several levels of XML-oriented granularity, and stepwise programmability and media enrichment. The site contains complete textbook, contextual and general discussion/feedback areas, internally and externally produced slideshows/video footage, topical news service and student self tests based on simple question-and-answer pages and multiple choice exercises with automated feedback. It has links to the externally hosted Kodak Micra software for distance analysis and comment on high resolution X-ray images, e.g. images of the various sections of Catphan500 (The Phantom Laboratory, New York). The students may then demonstrate the various quality control procedures on their PC in dialogue with the censors. They are also trained in the calculation of CTDIw, DLP and effective dose for various CT examinations, based on free software (Impact/NRPB, London). The students have to pass certain landmarks through the study. The answers and all correspondence with the censors are stored in the students’ digital files.
