This image shows the depolarization times of a patient-specific heart.

This is the result of a simulation coupling the electrophysiology-mechanical simulation.

For different reasons, the myocardial tissue can produce a disorder in the electrical conduction of the heart, thus causing a cardiac arrhythmia. When the arrhythmia is life-threatening, cardiologists need to ablate bthe area responsible for the pathology ased on radio-frequency (RF).

This simulator has been developed at the end of my Ph.D. It includes two main steps: a catheter navigation in the cardiovascular system, and a second step of electrophysiology mapping. Using an hybrid (CPU-GPU) multihreaded architecture, this training system ensures a high level of interactivity and realism.

This visualization is done for simulating endovascular navigation.
