Disclosed herein is a system and method for dynamic validation, correction of registration for surgical navigation during medical procedures on a patient which involves confirmation of registration between one or more previously registered virtual objects, such as surgical tools etc. in a common coordinate frame of a surgical navigation system and an operating room, and intra-operatively acquired imaging during the medical procedure in the common coordinate frame. The method includes displaying intra-operatively acquired imaging of the surgical field containing the one or more real objects corresponding to the one or more previously registered virtual objects, with the real objects being tracked by a tracking system. The method overlaying a virtual image containing the previously registered virtual objects onto the intra-operatively acquired imaging, from the point of view of the intra-operatively acquired imaging, and detecting for any misalignment between any one of the one or more previously registered virtual objects contained in the virtual image and its corresponding real object contained in the intra-operatively acquired imaging.L'invention concerne un système et un procédé de validation dynamique et de correction d'enregistrement pour une navigation chirurgicale au cours d'interventions médicales sur un patient, comprenant la confirmation d'enregistrement entre un ou plusieurs objets virtuels préalablement enregistrés, tels que des outils chirurgicaux, etc., dans un cadre de coordonnées commun d'un système de navigation chirurgicale et une salle d'opération, et la procédure d'imagerie acquise en intra-opératoire pendant l'intervention médicale dans le cadre de coordonnées commun. Le procédé consiste à afficher les images acquises en intra-opératoire du champ chirurgical contenant lesdits un ou plusieurs objets réels correspondant auxdits un ou plusieurs objets virtuels préalablement enregistrés, les objets réels étant suivis par un système de suivi.
