3D visualization methods to guide surgery for Parkinson's disease.

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.

Virtual reality in ophthalmology training.

Current training models are limited by an unstructured curriculum, financial costs, human costs, and time constraints. With the newly mandated resident surgical competency, training programs are struggling to find viable methods of assessing and documenting the surgical skills of trainees. Virtual-reality technologies have been used for decades in flight simulation to train and assess competency, and there has been a recent push in surgical specialties to incorporate virtual-reality simulation into residency programs. These efforts have culminated in an FDA-approved carotid stenting simulator. What role virtual reality will play in the evolution of ophthalmology surgical curriculum is uncertain. The current apprentice system has served the art of surgery for over 100 years, and we foresee virtual reality working synergistically with our current curriculum modalities to streamline and enhance the resident's learning experience.
