L’imagerie par r\u00e9sonance magn\u00e9tique (IRM) oculaire est une technique performante pour le diagnostic des pathologies du globe oculaire. Sa r\u00e9solution est toutefois limit\u00e9e par des art\u00e9facts induits par les mouvements involontaires de l’\u0153il.<\/p>\n\n\n\n

Ce travail de bachelor, s’inscrivant dans le projet de recherche \u00ab 2.0 MR-Eye \u00bb, visait \u00e0 surmonter cet obstacle.<\/p>\n\n\n\n

L’objectif consistait \u00e0 concevoir, fabriquer et caract\u00e9riser un prototype, nomm\u00e9 MR-Eye, capable de positionner de mani\u00e8re stable, fiable et confortable des \u00e9lectrodes d’\u00e9lectrooculographie (EOG) sur le visage d’un patient afin d’enregistrer ses mouvements oculaires en environnement IRM.<\/p>\n\n\n\n

Le prototype MR-Eye devait r\u00e9pondre \u00e0 une double contrainte : assurer un contact \u00e9lectrode-peau fiable pour un enregistrement de signaux ergonomique et confortable pour le patient, tout en garantissant une compatibilit\u00e9 totale avec l’environnement IRM.<\/p>\n\n\n\n

Cette exigence imposait l’utilisation de mat\u00e9riaux non ferromagn\u00e9tiques afin de pr\u00e9venir les risques s\u00e9curitaires, de ne pas d\u00e9grader la qualit\u00e9 de l’image par leur susceptibilit\u00e9 magn\u00e9tique et de minimiser la g\u00e9n\u00e9ration d’art\u00e9facts.<\/p>\n\n\n\n

Ce travail a permis de d\u00e9velopper et de valider un concept de dispositif modulaire, fonctionnel pour le monitoring EOG.<\/p>\n\n\n\n

Cependant, le prototype est jug\u00e9 incompatible avec l’imagerie \u00e0 haute r\u00e9solution. En effet, il g\u00e9n\u00e8re des art\u00e9facts significatifs qui pourraient d\u00e9grader la qualit\u00e9 des images des structures oculaires, qualit\u00e9 que ce projet visait pr\u00e9cis\u00e9ment \u00e0 am\u00e9liorer.<\/p>\n\n\n\n
