To correctly analyze distribution and changing rules of magnetic field in the brain under transcranial magnetic stimulation,and to obtain individualized design of the coil,magnetic field analyzing system of transcranial magnetic stimulation was designed.A circuit-magnetic field coupling analysis was made to analyze the whole pulse magnetic field progress through using finite element method and establishing a real head model,and the effect in the brain with different coil parameters was simulated.Then database technology was applied to realize automatic optimization of the coil parameters according to requirements of the clinic stimulation.This analysis is proved to be reliable and can provide foundation for making the coil stimulation and choosing the magnetic field of clinic stimulation.
