Stereotactic methods have been successfully used for the treatment of a wide range of neurological disorders. The main difficulties experienced with the current systems are their cumbersome frames and their time consuming positioning procedures. The South African Medical Research Council/University of Cape Town Biostereometrics Group, together with the Department of Neurosurgery of the University of Cape Town, in an attempt to overcome the problems associated with the present stereotactic guidance frames, have developed a very simple probe pointing device. The Cape Town Stereotactic Pointer (CTSP) is based on stereophotogrammetric principles but uses computed tomography as the imaging and measuring medium.
