Medical simulation

Medical simulation has been a very active research field for the past ten years. The ultimate goal is to provide medical students with realistic simulators that reacts like actual human patients.

One of the most challenging task in medical simulation is to realistically model soft organs and tissues, and their interaction with surgical instruments, requiring real-time solutions to complex problems like physical modeling, collision detection, ...

We continue our contribution to the development of medical simulators. We have recently concentrated our effort on the design of a cataract surgery simulator in ophthalmology. The first step of the operation (namely capsulhorexis) has been modeled. We now have a realistic real-time behavior of the capsule and its interaction with the surgical instruments. The next step will be the realistic modeling of the lens. A first approach based on finite-element modeling has been investigated. It allows for an accurate simulation of the phacoemusification procedure (breaking of the lens).

We began a collaboration with Magritt project at INRIA on the realistic simulation of brain aneurysm embolization. A first project, named "`simple"' was proposed for ARC. We wish to shear our knowledges about medical image processing for Magritt and physically based simulation for Alcove. We would like to propose simulation as a tool, not only for education, but also for planning.

Following our first experience with the SPORE real-time simulation engine, we have started the development of a next generation engine (called SOFA) that will be more flexible than the previous one. This development is a joint-effort between Alcove, Asclepios (INRIA Sophia), Evasion (INRIA Grenoble) and the Sim group@CIMIT (Boston, USA). Our purpose is also to collaborate with other worldwide research teams involved in simulation.
