Using digital imaging and standard computer technology seemed to the group of experts a clever way to simplify and ease the examination process. In the beginning of 2001, the Medical Informatics Service (SIM, part of the Radiology Department of Geneva University Hospitals) was asked to build a basic system that would enable the examination process to take place in two rooms previously dedicated to computer training. It was then realized by the IntRad / BolinOS team in charge of the Department's intranet and internet websites.

Each candidate had to have access to one workplace from which he could browse the cases instead of walking from and to the back-lit displays previously used. The quality of the final image display had to be good enough to contain pertinent radiological information, while using the standard computers, web browsers, internet connnectivity  and CRT displays available to us.

The training of radiologists in Switzerland is supervised by the FMH Swiss Medical Association wich organizes two examination stages in order to assess the future-radiologists' level of  knowledge, towards the obtention of an official professional certification. The second-part examinations offer the candidates to answer questions related to radiological-pathology, through image analysis and description. This is done through case presentation but also through open-field (the quiz) and multiple-choice (the superquiz) questions. Every year the quiz is composed of 30 questions, and the superquiz is composed of 15 questions. Both contain a case's key radiological images selected by a group of expert radiologists.

In the past all these images had to be manually copied on film and displayed on wall-mounted backlit-screens located in a long corridor of Geneva's University Hospitals' Department of Radiology. Each candidate had then to walk from one case to another in order to respond to the different questions.
