Abstract
A system and method may include determining a target stimulation volume based on modifying a patient population image for which an efficacious volume had been determined. A system and method for suggesting stimulation devices may include determining which stimulation device is capable of producing an output volume of activation that most closely matches the target volume. A system and method for facilitating selection of stimulation parameters may include graphically identifying a maximum volume in which tissue is stimulatable by an implanted stimulation device. A system and method may pre-compute volumes of activation that result from a predetermined modification of programming settings. A system and method may transmit stimulation programming settings from a stimulation programming module to a stimulation generating device.
