Objective. Transcranial Direct Current Stimulation (tDCS) is a technique where a weak current is passed through the electrodes placed on the scalp. The distribution of the electric current induced in the brain due to tDCS is provided by simulation toolbox like Realistic volumetric Approach based Simulator for Transcranial electric stimulation (ROAST). However, the procedure to estimate the total current density induced at the target and the intermediary region of the cortex is complex. The Systematic-Approach-for-tDCS-Analysis (SATA) was developed to overcome this problem. However, SATA is limited to standardized (MNI152) headspace only. Here we develop individual -SATA (i-SATA) to extend it to individual head. Approach. T1-weighted images of 15 subjects were taken from two Magnetic Resonance Imaging scanners of different strengths. Across the subjects, the montages were simulated in ROAST. i-SATA converts the ROAST output to Talairach space. The x, y ...

i-SATA：基于 MATLAB 的工具箱，用于估计单个大脑中经颅直流电刺激产生的电流密度。

客观的。经颅直流电刺激 (tDCS) 是一种通过放置在头皮上的电极的微弱电流的技术。由于 tDCS 在大脑中感应的电流分布由模拟工具箱提供，例如基于现实体积方法的经颅电刺激模拟器 (ROAST)。然而，估计在目标和皮层中间区域感应的总电流密度的过程很复杂。开发了用于 tDCS 分析的系统方法 (SATA) 来克服这个问题。但是，SATA 仅限于标准化 (MNI152) 顶空。在这里，我们开发了单独的-SATA（i-SATA）以将其扩展到单独的磁头。方法。15 名受试者的 T1 加权图像取自两台不同强度的磁共振成像扫描仪。在所有受试者中，蒙太奇都是在 ROAST 中模拟的。i-SATA 将 ROAST 输出转换为 Talairach 空间。x，y ...
