Computer Assisted Interventionist Imaging: Application To The Vertebral Column Surgery
B. Mazier, S. Lavallée, Philippe Cinquin · 2005
Included into a Computer Assisted Medical Interventionist program (6),(7), this paper presents a matching-based method that allows to reproduce in real conditions a positioning act previously simulated on a 3D modelling of medical images. A matching procedure is achieved by interactively comparing an on-line video image of the real world with a simulated video image, synthesized from the 3D modelling through the knowledge of geometrical camera parameters. The rigid coupling between the video camera and a physical guide performs by itself the desired positioning. The clinical application that we envisage is the vertebral column surgery.
