  • Device for noninvasive stereotactic immobilization in reproducible position
    Patent number: 5702406
    Abstract: The present invention pertains to a device for noninvasive, stereotactic immobilization in reproducible position with a head ring providing a firm reference system, a mask consisting of several parts attached to the head ring. The mask is individually adapted to the anatomical contours of a patient, and has mask parts connected with one another as well as with the reference system. The connections enable adjusting the relative position of the mask parts to one another.

  • Fixation pin for fixing a reference system to bony structures
    Patent number: 5643268
    Abstract: The present invention pertains to a fixation pin for fixing a reference system, especially a head ring for stereotactic treatment, to bony structures, which pin has a shaft made of plastic material with an outside thread, a coupling shoulder for a screwdriver and a point holder, and it has a point, which is held by the point holder. The point has a conical front end, in which case the point is made of a semiprecious stone material.

  • Device for detecting the position of radiation target points
    Patent number: 5628315
    Abstract: The present invention pertains to a device for detecting the position of radiation target points with an anchoring means for attachment to a patient reference system, especially to a stereotactic immobilization system, e.g., a head ring, and with a labeling means, arranged on the anchoring means, for at least one point of coordinates in various three-dimensional projections, in which case the labeling means consists of several computer-printed surface materials, which plot the point of coordinates in a three-dimensional manner.
