Abstract: Provided is a method for determining a position of an imaged anatomical body part of a patient. The method includes acquiring patient image data describing a digital image of at least part of a reference device and the anatomical body part, acquiring reference device model data describing a model of at least one of at least one internal surface or at least one external surface of the reference device, determining, —based on the patient image data and the reference device model data, reference device image position data describing a relative position between the reference device and the anatomical body part, acquiring reference device tracking data describing a position of the reference device in the tracking reference system, and determining, based on the reference device image position data and the reference device tracking data, body part tracking data describing a position of the anatomical body part in the tracking reference system.

Abstract: Provided is a data processing method for determining rotation by a marker device of a medical tracking system about its mount. The data processing method includes acquiring a first marker device position dataset which represents a position of the marker device before a movement of the marker device. A second marker device position dataset is acquired which represents the position of the marker device after a movement of the marker device. A marker device displacement dataset is calculated, which represents the displacement of the marker device, from the first and second marker device position datasets. At least one axis of rotation of the marker device displacement dataset is calculated. A determination is made whether or not the marker device is rotated about its mount from the position of the at least one axis of rotation relative to the marker device.

Abstract: Disclosed is a computer-implemented method for determining a target position of an X-ray device which encompasses acquiring image data describing an anatomical structure of a patient, for example, by means of a 3D scan, and registering the image data relative to a coordinate system of the patient, for example by means of a navigation system (embodied by registered image data). Furthermore, a trajectory of an implant positioned within the anatomical structure relative to the patient coordinate system is acquired (embodied by trajectory data). A target position of an X-ray device for acquiring an X-ray image of at least part of the implant is determined based on the registered image and the acquired trajectory of the implant (embodied by X-ray device position data).
