摘要

The invention relates to a registration system (13) for registering an imaging device (2) like an x-ray C-arm device with a tracking device (4) like an optical shape sensing tracking device. An object detection unit (5) is adapted to a) allow a user to add markers to an image of an object for indicating arbitrary positions on the object and b) provide a representation of the object based on the added markers, wherein a registration unit (6) determines registration parameters based on a location of the object tracked by the tracking device and on the location of the representation. This kind of registration can be performed with any object being visible for the user in the image, thereby permitting to use a wide variety of objects for the registration.
