La connaissance de la morphologie des faisceaux de fibres blanches, qui connectent des régions cérébrales distantes, est indispensable à la compréhension du fonctionnement cérébral. La tractographie par IRM de diffusion reconstruit indirectement cette anatomie à partir d'algorithmes mathématiques complexes. Après une revue des méthodes proposées pour la validation de la tractographie, nous proposons une méthode originale basée sur la reconstruction 3D de faisceaux disséqués. Notre méthode, FIBRASCAN, utilise des acquisitions itératives de surface en cours de dissection. Les faisceaux étaient segmentés sur chaque surface puis reconstruits par empilement. Un support rigide permettait le recalage entre surfaces puis vers l'IRM. Nous avons démo...
