Title
(EN) TOOL TRACKING DURING SURGICAL PROCEDURES
(FR) SUIVI D'OUTIL DURANT DES INTERVENTIONS CHIRURGICALES
Abstract
(EN)
A system and method for tracking a surgical implement in a patient can have an imaging system configured to obtain sequential images of the patient, and an image recognition system coupled to the imaging system and configured to identify the surgical implement in individual images. The image recognition system can be configured to identify the surgical implement relative to the patient in one of the images based, at least in part, on an identification of the surgical implement in at least one preceding one of the sequential images, and a probabilistic analysis of individual sections of the one of the images, the sections being selected by the image recognition system based on a position of the surgical implement in the patient as identified in the at least one preceding one of the images.
(FR)
L'invention concerne un système et un procédé de suivi d'un outil chirurgical dans un patient, lesquels système et procédé peuvent avoir un système d'imagerie configuré pour obtenir des images séquentielles du patient, et un système de reconnaissance d'image couplé au système d'imagerie et configuré pour identifier l'outil chirurgical dans des images individuelles. Le système de reconnaissance d'image peut être configuré pour identifier l'outil chirurgical par rapport au patient dans l'une des images sur la base, au moins en partie, d'une identification de l'outil chirurgical dans au moins une image séquentielle précédente parmi les images séquentielles, et d'une analyse probabiliste de sections individuelles de l'une des images, les sections étant sélectionnées par le système de reconnaissance d'image sur la base d'une position de l'outil chirurgical dans le patient tel qu'identifié dans la ou les images précédentes parmi les images.
