| description | The present invention relates to interventional device tracking. In order to provide a facilitated tracking of instruments with less X-ray radiation, a system (10) for tracking an interventional device is provided that comprises an interface unit (12), a data storage unit (14), a processing unit (16) and an output unit (18). The interface unit is configured to provide at least two current 2D images of a region of interest of a subject acquired with optical cameras in at least two different viewing directions. The 2D images show an instrument in the region of interest, wherein the instrument has a geometry that comprises a rigid cylinder. The processing unit is configured to identify at least one straight line, representing the instrument, in each of the at least two current 2D images. The processing unit is further configured to determine an instrument 3D line based on the identified at least one straight line in each of the at least two current 2D images. The processing unit is also configured to project the instrument 3D line on pre-interventional 3D data of the region of interest of the subject generating a combined navigation image. The output unit is configured to provide the combined navigation image to the user. |
