Knowing the orientation of directional deep brain stimulation electrodes enables imaging-based adjustment of the stimulation settings. A rotational X-ray based examination was developed to determine the electrodes orientation. By identifying the patient´s 0° axis and the electrode´s rotation using the "iron sights"-sign, the exact orientation of the electrode in relation to the ACPC-line is given. The presented imaging approach offers a reliable diagnostic tool for visualization of the implanted DBS electrode orientation in clinical routine.
了解定向性脑深部刺激电极的方向有助于基于成像对刺激设置进行调整。已开发出一种基于旋转X射线的检查方法来确定电极方向。通过利用“准星”标志识别患者的0°轴和电极的旋转情况，可得出电极相对于前连合-后连合线（ACPC线）的确切方向。所提出的成像方法为临床常规中可视化植入的脑深部刺激电极方向提供了一种可靠的诊断工具。
