摘要：
The present invention relates to navigating an interventional device. In particular, the invention relates to a system for navigating an interventional device within a tubular structure of an object, a method for navigating an interventional device within a tubular structure of an object as well as a computer program element and a computer-readable medium. In order to provide enhanced information to the user in an easily comprehensible manner while keeping the X-ray dose to a minimum, a system and a method for navigating an interventional device within a tubular structure of an object are provided, wherein the method comprised the following steps: a) Acquiring 2D X-ray fluoroscopy image data in one projection geometry of a region of interest of the tubular structure b) detecting the interventional device in the 2D X-ray image c) determining the 2D position of the interventional device in the 2D X-ray image d) registering the at least one 2D X-ray image with a previously acquired 3D dataset of the region of interest of the tubular structure e) mapping the determined 2D position of the interventional device to a position in the 3D dataset f) extracting local 3D parameters of the tubular structure at the position of the interventional device g) generating navigational information on behalf of the determined 3D position of the interventional device and the extracted local 3D parameters and h) providing the navigational information to the user.
