作为一种非侵入性脑刺激技术,经颅直流电刺激(tDCS)由于其方便的实现和调节大脑功能,近年来在研究和临床应用中受到越来越多的关注。在本文中,我们提出了一种新颖的多电极 tDCS 电流配置模型,可在安全约束下最小化总误差。将模型重写为线性约束最小化问题后,我们开发了一种基于乘子交替方向法(ADMM)的高效数值算法。数值实验表明该方法在准确性和聚焦性方面具有巨大潜力。
As a non-invasive brain stimulation technology, transcanial direct current stimulation (tDCS) has been recently attracting more and more attention in research and clinic applications due to its convenient implementation and modulation of the brain functionality. In this paper, we propose a novel multi-electrode tDCS current configuration model that minimizes the total error under the safety constraints. After rewriting the model as a linearly constrained minimization problem, we develop an efficient numerical algorithm based on the alternating direction method of multipliers (ADMM). Numerical experiments have shown the great potential of the proposed method in terms of accuracy and focality.
