Visual Inspection Of Dbs Efficacy

A key problem in Deep Brain Stimulation (DBS) is determining the optimal parameters for clinical outcome. Current knowledge does not provide a complete deterministic model of DBS neurophysiology. While multiple parameters may influence clinical outcomes in DBS, this paper explores spatial correlation of volume of tissue activated (VTA) to Unified Parkinson’s Disease Rating Scale (UPDRS) scores. Surface-to-surface Euclidean distance metrics between VTA and selected brain nuclei are used in a linked 3D and parallel coordinates view of patient outcome in UPDRS. We then present our approach based on semivariograms, which can be used interactively within nuView to show spatial correlation of patient outcomes with VTA. As a third component, nuView provides a unique visualization of an ensemble of electrode placements to reduce clutter and emphasize electrodes with spatially similar VTA.
