インターベンション装置をナビゲートするシステム及びその作動方法、コンピュータプログラムエレメント並びにコンピュータ可読媒体

Japanese Patent JP5685605

B2

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.
