Title
(EN) SYSTEM AND METHOD OF UTILIZING ONE OR MORE IMAGES OF AN EYE IN MEDICAL PROCEDURES
(FR) SYSTÈME ET PROCÉDÉ D'UTILISATION D'UNE OU DE PLUSIEURS IMAGES D'UN ŒIL DANS DES INTERVENTIONS MÉDICALES
Abstract
(EN)
The disclosure provides a system that may acquire, via an image sensor, an image of an eye of a person; may determine a location of an iris of the eye from the image; may determine a position of a suction ring from the image; may display, via a display, the image; may display, via the display, a first graphic overlay on the image that indicates the location of the iris of the eye; may display, via the display, a second graphic overlay on the image that indicates the position of the suction ring; may determine multiple iris structures from the image; may determine an orientation of the eye based at least on the multiple iris structures from the image; and may display, via the display, information that indicates the orientation of the eye.
(FR)
L'invention concerne un système qui permet : d'acquérir, par l'intermédiaire d'un capteur d'image, une image d'un œil d'une personne ; de déterminer l'emplacement de l'iris de l’œil à partir de l'image ; de déterminer la position d'un anneau d'aspiration à partir de l'image ; d'afficher l'image, par l'intermédiaire d'un dispositif d'affichage ; d'afficher, par l'intermédiaire du dispositif d'affichage, un premier recouvrement graphique sur l'image qui indique l'emplacement de l'iris de l’œil ; d'afficher, par l'intermédiaire du dispositif d'affichage, une seconde superposition graphique sur l'image qui indique la position de l'anneau d'aspiration ; de déterminer de multiples structures d'iris à partir de l'image ; de déterminer une orientation de l’œil sur la base au moins des multiples structures d'iris à partir de l'image ; d'afficher, par l'intermédiaire du dispositif d'affichage, des informations qui indiquent l'orientation de l’œil.
