Abstract

A system and method for displaying a volume of activation (VOA) may include a processor that displays via a display device a model of a portion of a patient anatomy that includes anatomical structures, displays via the display device and overlying the display of the model a VOA associated by the processor with a set of anatomical stimulation parameter settings, the display of the VOA, and graphically identifies interactions between the displayed VOA and a first subset of the anatomical structures associated with one or more stimulation benefits and a second subset of the anatomical structures associated with one or more stimulation side effects, where the graphical identifications differ depending on whether the interaction is with the first subset or the second subset.
