Title (EN) SYSTEM AND METHOD FOR IMAGE SEGMENTATION IN GENERATING COMPUTER MODELS OF A JOINT TO UNDERGO ARTHROPLASTY
(FR) SYSTÈME ET PROCÉDÉ DE SEGMENTATION D'IMAGE LORS DE LA GÉNÉRATION DE MODÈLES INFORMATIQUES D'UNE ARTICULATION DEVANT SUBIR UNE ARTHROPLASTIE
Abstract: front page image
(EN)Systems and methods for image segmentation in generating computer models of a joint to undergo arthroplasty are disclosed. Some embodiments may include a method of partitioning an image of a bone into a plurality of regions, where the method may include obtaining a plurality of volumetric image slices of the bone, generating a plurality of spline curves associated with the bone, verifying that at least one of the plurality of spline curves follow a surface of the bone, and creating a 3D mesh representation based upon the at least one of the plurality of spline curve.
(FR)L'invention porte sur des systèmes et des procédés de segmentation d'image lors de la génération de modèles informatiques d'une articulation devant subir une arthroplastie. Certains modes de réalisation peuvent comprendre un procédé de division d'une image d'un os en une pluralité de régions, le procédé pouvant comprendre l'obtention d'une pluralité de tranches d'image volumétrique de l'os, la génération d'une pluralité de courbes splines associées à l'os, la vérification du fait qu'au moins l'une de la pluralité de courbes splines suit une surface de l'os et la création d'une représentation maillée en 3D sur la base de la au moins une parmi la pluralité de courbes splines.
