A dataset of image templates of deep brain stimulation electrodes for postoperative 3.0 T MRI

Magnetic resonance imaging (MRI) can be used to localize the deep brain stimulation (DBS) electrodes after surgery. A template of the electrode artifact arising from signal void and distortions in the MR images could be matched to obtain the electrode locations. The existing electrode artifact template lacks a detailed description of its construction process and does not distinguish bilateral artifacts. In this dataset, we describe the use of postoperative T1-weighted 3.0 T MRI data in patients implanted with bilateral DBS to generate bilateral artifact templates. The templates may facilitate better localizations of the electrodes after surgery, which is beneficial for disease management or mechanism study. The hemisphere-specific electrode artifact template dataset is shared on the freely accessible platform of Mendeley Data.

磁共振成像（Magnetic Resonance Imaging，MRI）可用于术后定位脑深部电刺激（Deep Brain Stimulation，DBS）电极。通过匹配MR图像中由信号空穴与图像畸变产生的电极伪影模板，可确定电极的空间位置。现有电极伪影模板缺乏构建流程的详细说明，且无法区分双侧伪影。本数据集针对植入双侧DBS的患者，采用术后3.0T T1加权MRI数据生成双侧伪影模板。该模板可优化术后电极定位精度，有助于疾病管理与机制研究。本半球特异性电极伪影模板数据集已共享至可免费访问的Mendeley Data平台。
