ABSTRACT:
The invention relates to a method of localizing an instrument relative to three-dimensional corporeal data, particularly for stereotaxis, comprising the following steps: connecting internal markers fixedly to the body to define an intracorporeal, spatial reference system, implementing an analytical scan of the body including the internal markers to determine the positions of the three-dimensional corporeal data obtained from analytical scan in the intracorporeal reference system defined by the internal markers, implementing a referencing step, whereby position and orientation of the intracorporeal reference system defined by the internal markers relative to an extracorporeal reference system defined by external markers is determined and said external markers is located outside of the body in a fixed spatial relationship, determining the position and orientation of an instrument in the extracorporeal reference system with the aid of the external markers and a instrument markers attached to the instrument, and computing from said position and orientation in the extracorporeal reference system the position and orientation of the instrument in the intracorporeal reference system via the relationship between the intracorporeal and the extracorporeal reference systems known from the referencing step, as well as a markers device and a device for referencing.
