Mixed-Reality Guidance for Brain Stimulation Treatment of Depression

摘要

Depression affects more than 16 million American adults and more than half do not respond to medication. Transcranial magnetic stimulation (TMS) is an important anti-depressant treatment that targets specific brain circuits responsible for mood and behavior. TMS efficacy and risk is strongly linked to correct TMS coil placement and can be significantly improved by accurate neuronavigation. In this paper, we present tools for the development of a novel mixed reality neuronavigation setup that allows the TMS operator to view the patient's brain anatomy directly overlaid on the head. This is performed by integrating patient tracking and visualization of brain magnetic resonance imaging (MRI) to provide a streamlined visualization of the patient's anatomy in a single immersive environment.
