Abstract The therapeutic benefits are strongly related to the location accuracy of the deep brain stimulation (DBS) electrodes in the target. The postoperative electrode positions cannot be accurately located because of their artifacts. An electrode position estimation method was developed using the artifacts to judge the electrode position relative to the target nucleus to improve the therapeutic effect and the electrode positioning and to help neurosurgeons prepare appropriate surgery plans. Magnetic resonance imaging (MRI) data for artifact locations in a phantom and in 10 Parkinson's disease (PD) patients using a correlation coefficient show that this method can accurately measure the electrode position with a predictable error.
