| Abstract: | A model of spherical head has been constructed, which consists of skull and interior tissue. Bring forward the method that combine traditional calculation method with FDTD to calculate the induced electric fields in brain during magnetic stimulation. Different coil shapes such as circular and 8-shaped were considered and induced electric fields were given. The results provide some preliminary theoretical basis for further research on the optimum methods and mechanism of the brain magnetic stimulation. |
