The disclosure relates to a system for tracking the position of a target object. A marker arranged on the target object and an additional control marker are tracked by a tracking device secured to the robot arm. The control marker is arranged in a known specified three-dimensional positional relationship with the tracking device. During the tracking of the position of the target object, the specified three-dimensional positional relationship between the tracking device and the control marker is measured. In the event of a difference between the measured and the real specified three-dimensional positional relationship, a corresponding signal is generated depending on the difference.

System and method for tracking the position of a target object

In an embodiment, a method includes acquiring a first image data set of the patient, via an X-ray apparatus, at a first time point during the operative intervention, the first image data set including the reference structure, the anatomical structure and the reference system between the reference structure and the anatomical structure; acquiring a second image data set of the patient at a second time point, the second image data set including at least the reference structure; registering the second image data set to the first image data set. As a result of the registering of the second image data set to the first image data set, a registered second image data set is determined. Finally, an embodiment of the method includes determining the validity of the reference system by a comparison of the registered second image data set with the first image data set.
