摘要
An intracerebral current simulation method comprises: a first step of providing head image data that includes at least a part of the brain out of tomographic image data of a patient; a second step of forming a three-dimensional brain model comprising micro-polyhedron units which are obtained by dividing at least one region constituting the brain out of the head image data provided in step 1 into micro-elements; a third step of providing first information which includes conditions under which a coil is placed on the patient's head, an electric current is applied to the coil so as to apply magnetic stimulation to the patient's brain, and the patient's reaction to the magnetic stimulation is observed, the conditions being at least the condition of a position and orientation of the coil, the condition of the electric current applied to the coil, and the condition of a structure relating to a generated magnetic field of the coil; and a fourth step of calculating an eddy current or electric field induced inside each of the micro-polyhedron units of the three-dimensional brain model on the basis of the first information provided in the third step and second information which includes conductivity assigned to each micro-polyhedron unit.
