FLUORO-NAVIGATION SYSTEM FOR NAVIGATING A TOOL RELATIVE TO A MEDICAL IMAGE

摘要

The invention relates to a fluoro-navigation system for navigating a tool relative to a medical image, comprising: - a motorized X-ray imaging system adapted to acquire a plurality of images of a region of interest of a patient, the position of each image being known in a referential of the imaging system, - a localization system; - a registration phantom (30) comprising a plurality of radiopaque fiducials (31); - a tracker (20) adapted for being tracked by the localization system; - a processor configured for receiving the plurality of images acquired by the motorized X-ray imaging system and for reconstructing a 3D medical image from said images using radiopaque fiducials (31) visible in the plurality of images; - a base (10) made of a substantially radiotransparent material, the base (10) being adapted to be rigidly secured to a patient's bone (B) and comprising a reproducible fixation system for attaching said registration phantom (30) and/or said tracker (20).
