摘要:
明确经颅直流电刺激(tDCS)治疗时颅内电场数值分布,有助于准确控制治疗处方剂量,确保颅内目标区的电场能够高于有效刺激阈值,提高治疗处方对病人治疗的有效性。本文采用商用工具软件COMSOL,完成颅内电场边值问题有限元数值解,计算出了tDCS治疗时颅内电场强度分布,并以图形化显示治疗处方在目标区域电场剂量的有效数值。本文介绍的方法可用于tDCS治疗处方方案优化研究,也可用于分析其它电刺激治疗是否形成有效刺激的电场强度。
Abstract:
Abstract: Clarifying the value distribution of intracranial electric field during transcranial direct current stimulation (tDCS) treatment can help accurately control the prescribed dose of treatment, ensure that the electric field in the intracranial target area is higher than the effective stimulation threshold, and improve the effectiveness of treatment prescriptions for patients. In the study, the finite element numerical solution of the boundary problem of intracranial electric field is obtained by the commercial software COMSOL. The distribution of intracranial electric field intensity during tDCS treatment is calculated, and the effective value of electric field dose in the target area is graphically displayed. The proposed method can be used to optimize the prescription scheme of tDCS treatment, and to analyze whether other electrical stimulation treatment can reach the electric field intensity of effective stimulation.
