Title
(DE) AUTOMATISCHE MANIPULATION DES SICHTFELDS EINES BILDGEBUNGSGERÄTS AUF BASIS EINER VERFOLGTEN POSITION EINES MEDIZINPRODUKTS
(EN) AUTOMATED MANIPULATION OF IMAGING DEVICE FIELD OF VIEW BASED ON TRACKED MEDICAL DEVICE POSITION
(FR) MANIPULATION AUTOMATISEE DE CHAMP DE VISION DE DISPOSITIF D'IMAGERIE BASEE SUR UNE POSITION SUIVIE DE DISPOSITIF MEDICAL
Abstract
(EN) Systems for navigating medical devices are provided. A patient is imaged while a medical device (110) is moved within the patient. A position of the moving medical device is detected within a coordinate system, a position of the imaging field of view relative to the patient is adjusted based on the detected medical device position, such that the relevant tissue region of the patient is within the field of view. For example, the field of view can be centered over the medical device or centered just distal to the medical device portion. The direction of view may be oriented at an angle perpendicular to the axis of the medical device or oriented at an angle parallel to the axis of the medical device portion.
(FR) Systèmes pour piloter des dispositifs médicaux. On crée une image d'un patient pendant qu'un dispositif médical (110) est déplacé à l'intérieur du patient. Une position du dispositif médical en déplacement est détectée dans un système de coordonnées, une position du champ de vision d'imagerie relatif au patient est réglée sur la base de la position détectée du dispositif médical, de telle sorte que la région de tissu adéquate du patient est comprise dans le champ de vision. Par exemple, le champ de vision peut être centré sur le dispositif médical ou centré de façon juste distale par rapport à la partie de dispositif médical. La direction de la vue peut être orientée à un angle perpendiculaire à l'axe du dispositif médical ou orientée à un angle parallèle à l'axe de la partie du dispositif médical.
