title: Photogrammetric target point determination in stereotaxy.
abstract: The photogrammetric determination of the target point in stereotactic operations enables a simplification of the photographic equipment and an avoiding of calculating errors during the operation. This is possible on the one hand by excluding the X-ray distortion also without distance taking and, on the other, by the use of a computer which is connected up to the stereocomperator. In addition to the continuous mathematical controls, a visual control of the spatial picture on the stereocomperator is possible.
