[A CT localization frame--an improved method for preoperative localization of intracranial processes].

A new CT localization equipment for cerebral processes is presented. As compared to the methods used until now it offers the advantage that no direct marking on the shaven skull must be provided. The parameters resulting during the CT examination with applied localization frame enable the preoperative localization at any desired time. A precondition is the use of an identical device by the surgeon. The use of the methods is explained.
