SYSTEM AND METHOD FOR TRACKING A NON-VISIBLE STRUCTURE OF A BODY

摘要

A monitoring system tracks the non-visible structure of a body in three dimensions. A tracker (508) obtains image information of the object and instruments (506) in its vicinity, all bearing 3D tracking markers (504). A controller spatially relates the image information with previously obtained scan data of the object revealing a non- visible structure (612') of the object. For the scan a fiducial reference detectable in the scan is removably attached to a location on the object. The scan data and image information is used by the controller to provide the user with real time information on the relative 3D locations and orientations of the instruments and the non-visible structure of the body. In a further embodiment the monitoring system may be used to model and track the changes in the body itself. In other embodiments, a model of the body and instruments is used to track contemplated actions and warn about possibly inappropriate instrument procedures.
