Major Difficulties of Stereotaxy

One of the major difficulties of stereotactic surgery is graphic conceptualization of the location of various treatment modalities inserted into brain and body structures. Furthermore, stereotactic surgery is essentially a blind surgical procedure with many complex geometric variables. The treating physician must have a method for accurately and rapidly calculating coordinates for a given target operative site located within the depths of the brain or body. These coordinates must be translated into three-dimensional reference coordinates for accurate positioning of various treatment modalities.
