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.
