Abstract: Three-dimensional image data generated for an object is representative of at least a portion of the object and of reference markings associated with the object. The reference markings have a known spatial relationship with a registration tracker tracked by a navigation system. Registration tracking data/object tracking data, each representative of at least one of a spatial location and a spatial orientation of the registration tracker/object tracker respectively, are provided. The object tracker has a fixed spatial relationship with the object. The relative position between the registration tracker and the object tracker is calculated from the registration tracking data and the object tracking data for a given point in time. Registered image data is generated representative of the location or the orientation of the object, taking into account the spatial relationship between the reference markings and the registration tracker, and the relative position between the registration tracker and the object tracker.

Abstract: A technique of registering image data of an object 112 with at least one of a location and an orientation of the object 112 is provided. A method embodiment of this technique comprises the step of providing three-dimensional image data generated for the object 112, the image data being representative of at least a portion of the object 112 and of reference markings 130 associated with the object 112. The reference markings 130 have a known spatial relationship with a registration tracker 122 adapted to be tracked by a navigation system 100. The method further comprises providing registration tracking data representative of at least one of a spatial location and a spatial orientation of the registration tracker 122 and providing object tracking data representative of at least one of a spatial location and a spatial orientation of an object tracker adapted to be tracked by the navigation system. The object tracker 124 has a fixed spatial relationship with the object 112.

Abstract: An adapter can be easily used to assist a surgical navigation system to determine the effector axis or the effector plane of a surgical device. The adapter has a body with a geometrical feature, the geometrical feature has a known relation with a navigation tracker device that can be attached to the adapter. When the adapter is held against a surgical device in a non-fixed manner, the effector axis or the effector plane of the device can be tracked by the surgical navigation system. The method includes a calibration method to determine the known relation between the effector axis or the effector plane and the location of the navigation tracker.
