Title
(EN) BONE ENTRY POINT VERIFICATION SYSTEMS AND METHODS
(FR) SYSTÈMES ET PROCÉDÉS DE VÉRIFICATION DE POINT D'ENTRÉE D'OS
Abstract
(EN) A method for verifying a bone entry point includes receiving a surgical plan that defines a target bone entry point and a first portion of a bone surface at least partially surrounding the target bone entry point; positioning an imaging device near an identified bone entry point; receiving, from the imaging device, an image of a second portion of the bone surface surrounding the identified bone entry point; comparing at least one feature of the first portion to at least one feature of the second portion to quantify a degree of similarity therebetween; and generating, when the quantified degree of similarity between the first portion and the second portion exceeds a threshold, a confirmation.
(FR) Un procédé de vérification d'un point d'entrée d'os comprend les étapes suivantes : recevoir un plan chirurgical qui définit un point d'entrée d'os cible et une première partie d'une surface osseuse entourant au moins partiellement le point d'entrée d'os cible ; positionner un dispositif d'imagerie à proximité d'un point d'entrée d'os identifié ; recevoir du dispositif d'imagerie une image d'une seconde partie de la surface osseuse entourant le point d'entrée d'os identifié ; comparer au moins une caractéristique de la première partie avec au moins une caractéristique de la seconde partie pour quantifier un degré de similarité entre elles ; et générer une confirmation lorsque le degré de similarité quantifié entre la première partie et la seconde partie dépasse un seuil.
