Lead-OR: A Multimodal Platform for Deep Brain Stimulation Surgery
2021
Deep Brain Stimulation (DBS) electrode implant trajectories are stereotactically defined using preoperative neuroimaging. To validate the correct trajectory, microelectrode recordings (MER) can be used to match the neuroanatomy with expected neurophysiological activity patterns, commonly using up to five trajectories in parallel. However, understanding their location in relationship to basal ganglia anatomy can be challenging. Here we present a tool that integrates resources from stereotactic planning, neuroimaging, MER and high-resolution atlas data to create a real-time visualization of the implant trajectory. We show a general correspondence between features derived from neuroimaging and electrophysiological recordings and present example use cases that demonstrate the functionality of the tool. The software toolbox is made openly available, extendable and holds translational potential in the field of stereotactic neurosurgery.
