A system for tracking a tracking element inside a body is provided. It includes a first tracking system, which includes a first tracking sensor for detecting the current position of a tracking element inside a body relative to a nominal position with respect to the first tracking sensor, and a second tracking system, which includes a second tracking sensor for determining the position of the first tracking sensor of the first tracking system relative to the second tracking sensor, and a control unit. The first tracking sensor is movable, and the control unit is configured to deliver a correction signal indicating a deviation of the current position of the tracking element relative to a nominal position with reference to the first tracking sensor. Further, a respective tracking method is provided. |
