Computer system for three-dimensional anatomic-physiological correlation during stereotactic and functional neurosurgery

This paper describes the automatic 3D-graphic possibilities that are supplied by the NDRS computer system (neurosurgical deep recording system) to facilitate the anatomic-physiological targeting during stereotactic and functional neurosurgery using deep recording. This software has been developed to substitute with a personal computer, the complex electronic equipment for deep brain electrical activity recording, display and processing. It also allows greater possibilities for on-line graphic analysis, automatic management of the recorded information and flexibility to implement different forms of signal analysis. Its new version can automatically show a 2D- and 3D-representation of the electrode track, with the superimposed electrophysiological findings, and the corresponding sagittal, coronal and axial view of a brain atlas, after its automatic scaling. The NDRS has already been successfully used in Spain and Cuba in more than 300 neurosurgeries, allowing to increase the targeting accuracy and safety.
