The global activity of the project in real-time simulation is mostly targeted toward surgical simulators. The key activity of the team is to provide complex, integrated protocols of surgical operations, involving several models and surgical aspects. This activity seems complementary, in our opinion, to most of classical simulation research, where results mostly deal with very specific aspects, i.e. collision detection, haptic, or mechanical models. In particular, our activity relates to that of EVASION project (on general-purpose simulation) and ASCLEPIOS project (research on organ mechanical models). We consider to be at the state-of-the-art level for mechanical modeling of deformable 1D models. This 1D model is very useful to accurately reproduce the behavior the tools used during interventional radiology procedures ( [29] ). Our research work is more and more related with medical simulation. We aim at creating new technological tools for surgery that rely on simulation and help the physician before and during the procedures. The targeted applications include ophtalmology, interventional radiology, liver surgery and dental surgery.
