Title (EN) SYSTEM AND METHOD FOR CALIBRATION FOR IMAGE-GUIDED SURGERY
(FR) SYSTÈME ET PROCÉDÉ POUR CALIBRER UNE OPÉRATION CHIRURGICALE GUIDÉE PAR IMAGE
Abstract: front page image
(EN)A method of calibrating a transformation of ultrasound data in an imaging system from a first coordinate system into a second coordinate system, the method comprising applying a transformation having parameters. The parameters are calibrated by imaging a planar object, extracting points corresponding to ultrasound rays intersecting the planar object, and fitting the parameters such that the points when transformed by the transformation describe a planar surface in the second coordinate system.
(FR)L’invention concerne un procédé de calibrage d’une transformation de données ultrasonores dans un système d’imagerie d’un premier système de coordonnées en un second système de coordonnées, le procédé comprenant une application d’une transformation comportant des paramètres. Les paramètres sont calibrés en imageant un objet plan, en extrayant les points correspondant à des rayons ultrasonores coupant l’objet plan, et en ajustant les paramètres de telle sorte que les points, une fois transformés par la transformation, décrivent une surface plane dans le second système de coordonnées.
