Synopsis

Deep Brain Stimulation (DBS) implants are implanted into target regions of the brain to treat symptoms of many neurological disorders. Postoperative Magnetic Resonance Imaging (MRI) scans are used to localize DBS leads, however, there are large, distorted artifacts surrounding the leads in the images. This study uses MRI phantoms to investigate the true location of a DBS lead relative to its artifact. The results will help researchers and clinicians know the actual locations of the lead tip and contacts from postoperative MRI scans to confirm the implant is correctly targeting the desired brain area.
