(EN) SYSTEM FOR ASSISTING A USER IN PLACING A PENETRATING DEVICE IN TISSUE
(FR) SYSTÈME POUR AIDER UN UTILISATEUR À PLACER UN DISPOSITIF PÉNÉTRANT DANS UN TISSU
Abstract
(EN) The invention relates to a system 8 for assisting a user in placing a penetrating device in tissue like a pedicle screw 7 in a vertebra's pedicle. The system generates a virtual view 20 from a penetrating device tip perspective within the tissue in the direction of a path 21 through a model of the tissue. The virtual view is generated based on tracking information indicating a pose of the penetrating device, the model and the path, wherein the virtual view is configured such that it indicates a direction in which the user should move the penetrating device while placing it in the tissue. For instance, it can show a virtual tunnel 801 which is arranged along the path. If a user like a surgeon is provided with such a virtual view, the user can position the penetrating device along the path with a significantly increased accuracy.
