Title (EN) SYSTEM AND METHODS FOR DETERMINING THE ORIENTATION AND POSITION OF A BONE-IMPLANTED ANCHOR
(FR) SYSTÈME ET PROCÉDÉS POUR DÉTERMINER L'ORIENTATION ET LA POSITION D'UN ANCRAGE IMPLANTÉ DANS L'OS
Abstract: front page image
(EN)In another aspect, the present invention relates to a method for determining the position and orientation of an anchor attached to the skull of a patient from a topographic image of the anchor acquired therefrom. In one embodiment, the method includes the steps of simulating an image of the anchor that matches the acquired topographic image of the anchor, determining the position and orientation of the anchor from the simulated image of the anchor, and determining the position and orientation of the anchor in the acquired topographic image of the anchor from the position and orientation of the anchor determined from the simulated image of the anchor. The simulating step comprises the step of modeling the anchor with an object that has a geometric shape simpler than that of the anchor.
(FR)L'invention concerne, dans un autre aspect, un procédé pour déterminer la position et l'orientation d'un ancrage fixé au crâne d'un patient à partir d'une image topographique de l'ancre acquise de celui-ci. Dans un mode de réalisation, le procédé comprend les étapes consistant à simuler une image de l'ancre qui correspond à l'image topographique acquise de l'ancre, déterminer la position et l'orientation de l'ancre à partir de l'image simulée de l'ancre, et déterminer la position et l'orientation de l'ancre dans l'image topographique acquise de l'ancre à partir de la position et de l'orientation de l'ancre déterminées à partir de l'image simulée de l'ancre. L'étape de simulation comprend l'étape consistant à modéliser l'ancre avec un objet qui présente une forme géométrique plus simple que celle de l'ancre.
