- 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.
