Analysis of electrode deformations in deep brain stimulation surgery

摘要

PurposeDeep Brain Stimulation (DBS) surgery is used to reduce motor symptoms when movement disorders are refractory to medical treatment. Postoperative brain morphology can induce electrode deformations as the brain recovers from an intervention. The inverse brain shift has a direct impact on accuracy of the targeting stage, so analysis of electrode deformations is needed to predict final positions.
