Keywords: MRI, segmentation, mesh reconstruction.

Abstract: pre and post-operative images like MRI can be modelized as voxel matrices, and a large number of algorithms from discrete geometry can be applied. Extracting a surface from such a description is also an interesting way to modelize the observed anatomical objects (organs, tissues, etc.) and facilitate the usage of geometrical and topological tools. I mainly worked on this approach, generating surfaces from the voxel description, then modifying the surface by integrating expert knowledge, related with geometry or topology, or extracting information to measure properties.

Main activity

I am a permanent member of the ALCoV team, ISIT, Université d'Auvergne, focusing on endoscopic surgery. ALCoV's scientific project brings new tools for surgical gesture training and decision making using virtual reality and for computer vision and augmented reality aided surgery. I am interested in extracting structured mesh from pre-operative images, to enrich the per-operative tools.
