Abstract

L'invention porte sur un dispositif, sur un système et sur un procédé pour mesurer la profondeur d'une couche de matériau, telle qu'une couche de plaque de vaisseau sanguin. Un faisceau de fibres optiques reçu dans un cathéter à ballonnet projette un point de laser en direction d'un miroir conique, qui réfléchit le point perpendiculairement sur la surface de la plaque. Le point de laser est renvoyé par réflexion à partir de la couche de plaque avec un profil d'intensité sensiblement gaussien. Le miroir conique dirige l'image reflétée vers le faisceau de fibres optiques, qui délivre l'image à un capteur. La profondeur de la couche de plaque peut être déterminée par comparaison du diamètre du profil d'intensité d'image à un ensemble de données normalisées pré-obtenu.
