  • Method of guiding a stereotaxic instrument at an intracerebral space target point
    Patent number: 4228799
    Abstract: A method for guiding a stereotaxic instrument at a target point in an intracerebral cavity comprising fixing detachable roentgenocontrast markers with respect to the patient's cranium, then effecting contrast roentgenography and determining the relative position of the markers and intracerebral reference points. Subsequently, the position of a target point with respect to the intracerebral reference points is determined and a physical model of the intracerebral cavity is constructed to include the points simulating the markers and a point simulating the target point. A stereotaxic apparatus is installed on the patient's head, the detachable roentgenocontrast markers are again fixed with respect to the patient's cranium, the position of the detachable markers with respect to the stereotaxic apparatus is identified and the positions of the detachable roentgenocontrast markers with respect to the stereotaxic apparatus are set-up in the model of the stereotaxic apparatus.
