Title
(EN) SYSTEMS AND METHODS FOR OBJECT POSITIONING AND IMAGE-GUIDED SURGERY
(FR) SYSTÈMES ET PROCÉDÉS POUR LE POSITIONNEMENT D'OBJET ET CHIRURGIE GUIDÉE PAR IMAGE
Abstract
(EN) A method for positioning an object positioned on a table (114a,114b) is provided. The method (700) may include: obtaining a plan image (702), the plan image illustrating a virtual surface of the object; obtaining a 3D image (704), the 3D image including a set of elements corresponding to the object; obtaining a registration result by registering the plan image and the 3D image (706); determining whether the object needs to be moved based (712); and in response to a determination that the object needs to be moved, causing the object to move according to the registration result (714).
(FR) L'invention concerne un procédé de positionnement d'un objet positionné sur une table (114a, 114b). Le procédé (700) peut consister à : obtenir une image dans le plan (702), l'image dans le plan illustrant une surface virtuelle de l'objet ; obtenir une image 3D (704), l'image 3D comprenant un ensemble d'éléments correspondant à l'objet ; obtenir un résultat d'alignement en alignant l'image dans le plan et l'image 3D (706) ; déterminer si l'objet doit être déplacé (712) ; et en réponse à une détermination établissant que l'objet doit être déplacé, amener l'objet à se déplacer selon le résultat d'alignement (714).
