In this paper we present 2D and 3D visualization techniques that are part of our ongoing effort to improve the accuracy of neurosurgical procedures such as ‘Pallidotomy’ and ‘Deep Brain Stimulation’ (DBS), which are performed to alleviate the symptoms of Parkinson's disease. The precise targeting and mapping of structures in the Basal Ganglia particularly the internal Globus Pallidus (GPi) using a combination of stereotactic frame- registered Magnetic Resonance Imaging (MRI) and intraoperative microelectrode recording (IMR) is key to the success of these procedures. We have designed a set of software components, including a knowledge- based system (KBS), a digital signal processing module and a 2D/3D imaging system with automated mapping paradigm, which will work in combination to improve upon the standards currently in use. The imaging system will be the focus of this publication.
