Abstract

For the use of an Operation Microscope, in computer-supported stereotactic surgery, a set of preoperative diagnostic data of a patient is first generated by means of an image-forming preoperative diagnostic procedure. The surgeon then plans the operation path on a central control unit and determines which of the stored diagnostic images are to be reflected into the observation optics of the operation microscope. During the operation, the operation microscope, arranged on a motorized support system, is caused to travel in a motorized manner along the established operation path, and the diagnostic images corresponding to the prior selection are selectively reflected into the observation optics of the operation microscope without a correlation having to be carried out of the respective individual coordinate systems.
