Title (EN) METHOD FOR ULTRASOUND GUIDANCE DURING CLINICAL PROCEDURES
(FR) PROCEDE DE GUIDAGE PAR ULTRASONS UTILISABLE DANS LE CADRE D'EXAMENS CLINIQUES
Abstract:
(EN) A method for generating quasi real-time feedback for the purpose of guiding surgical, terapeuthical or diagnostical procedures by means of ultrasound imaging is described. The location of a surgical tool, a terapeutic radiation field or a diagnostic energy field is related to the coordinate system of an intraoperative 2D and/or 3D ultrasound imaging system (and optionaly pre-operative MR/CT/X-ray data), thus allowing synchronized relations between data acquisition, tool movement and image visualizations.
(FR) La présente invention concerne un procédé permettant de produire quasiment en temps réel par imagerie ultrasonore des informations en retour destinées à guider des examens chirurgicaux, thérapeutiques ou diagnostiques. La localisation de l'instrument chirurgical, du champ de rayonnement thérapeutique ou du champ d'énergie de diagnostic est fondée sur un système de coordonnées fournies par un système peropératoire d'imagerie ultrasonore bidimensionnelle et/ou tridimensionnelle (et éventuellement de données préopératoires de résonance magnétique, de tomographie assistée par ordinateur ou de rayons X). Ce procédé permet ainsi d'établir des relations synchronisées entre la saisie des données, le mouvenent de l'instrument et les affichages d'images.
