Coupled Electro-Mechanical Model of the Heart
The contributions of this work are twofold. First, we developed an electrophysiological training simulator in SOFA which tackles the interactive issue in the context of cardiac arrhythmias. Coupled with this electrophysiology, we developed a mechanical model of the heart that can be personalized from MRI datasets.
Our simulations are based on the SOFA platform. SOFA is an open-source framework targeted at real-time simulation with an emphasis on medical simulation, mainly developed at Inria. A large choice of efficient solvers, hyperelastic or viscous material laws are already implemented in SOFA. Moreover, it enables interactivity during the simulation (pacing, surgery planning, …) and gives a good trade-off between accuracy and computational efficiency.
I worked as Ph.D. candidate at Inria during about three and half years (2010-2014) around cardiac electrophysiology. My Ph.D. thesis was a collaboration between two Inria teams, supervised by Herve Delingette (Asclepios) and Stephane Cotin (Shacra). My work aimed at modeling the cardiac electrophysiology, thus enabling us to simulate cardiac ablation in the framework of arrhythmia.
My work resulted in the development of the first simulator for interventional cardiology training. You can discover below a video presenting my work at Inria:
