Transcranial magnetic stimulation (TMS) treatment is an important non-invasive treatment option for depressive patients who do not respond to medication. Effective TMS treatment is dependent on accurate stimulation intensity calibration and coil positioning, which is best achieved through image-based neuronavigation. Unfortunately, most TMS treatments use generalized scalp measurements, which are faster and cheaper but less accurate and less effective than image-based neuronavigation. We present a mixed reality neuronavigation system that allows the clinician to view brain MRI and targeting information superimposed on the patient’s head for an accelerated and simplified procedure
