Iterative Full Head Finite Element Model for Deep Brain Stimulation
In order to understand the mechanisms involved in deep brain stimulation, several finite element models have been made using reduced part of the head and simplified boundary conditions. In this study, we present a method to obtain the potential created by deep brain stimulation while including the natural boundary conditions on the head surface. The use of an iterative procedure allows to have a detailed model of the electrode and of the surrounding tissues based on DT-MRI while applying more realistic boundary conditions than previous studies
