C.T. Aided Stereotaxy for Depth Electrod Implantation and Biopsy

We describe a computer program which facilitates the analysis of a series of C.T. scans made while a stereotaxic fram fixed to the patient. program has 2 modes of operation: The operator may select a region and determine the three-dimensional frame coordinate. The operator may select a set of frame coordinates and have the computer program display these at the appropriate sites on C.T. scans. If these sites are the positions of depth electrodes, then a recording of the epileptic spike activity may be displaye e appropriate sites on the scans.
