Abstract : Computer-based interactive medical simulation is a revolutionary technique for improving the effectiveness of medical practice while reducing risk exposure to patients. Although traditionally focused on training, such simulations could be used, in the near future, for planning and rehearsing complex interventions, or even for assisting physicians in the operating room. This manuscript presents a detailed overview of the multi-disciplinary field of medical simulation and highlights our various contributions in this area. After an overview, in Chapter I, of the many applications of medical simulation, Chapter II addresses the importance of models, from anatomical modeling (to create realistic, and potentially patient-specific, representations of the anatomy) to biomechanical modeling (to determine soft tissue characteristics, and define mathematical models of soft tissue deformation). Problems related to medical device modeling (such as flexible instruments of imaging devices) and physiological modeling (to compute blood flow for instance) are also addressed. Chapter III discusses the importance of tissue-tool interactions, which represent an essential part of medical procedures. Techniques for modeling such interactions, through efficient collision detection, and advanced contact mechanics, are presented in this chapter. In Chapter IV are presented several contributions in the area of validation, from the verification of algorithms for soft tissue deformation to the assessment of training systems. Chapter V is dedicated to the presentation of several prototypes of simulators that were developed during this research and Chapter VI presents an overview of our most recent efforts to design a framework for unifying key elements of real-time interactive simulations. This framework, called SOFA, is a multi-institutional collaborative work which has the potential to accelerate research, development and collaborations in the field of medical simulation. Finally, Chapter VII summarizes our different contributions to the field of medical simulation and presents challenging and exciting perspectives, in particular in the area of patient-specific interactive planning.
