PURPOSE: To attempt an electric current distribution to be determined not to be distorted from the actual distribution by specifying the surface that an electric power source exists and by limiting the capacity element positioned on the surface of the re-structure with reference to representation containing the morphogenetic structure of an object. CONSTITUTION: The measurement system of a component of the magnetic flux density in the radial direction is stored in a helium cryostat 4 placed on the cranial bones of a patient. Actually, the magnetic field is measured at three measuring points. For example, in the case of ictus epilepticus, it becomes an induced current caused by a stimulation of sense organs same as electric currents occurring in nature. These surfaces are specified with reference to the device 10 by an interactive display used by the operator for the center of an electric activity. Furthermore, a re-structure device 11 re-constitutes the density of an applied electric current from measured values of magnetic flux density of several picture elements at the same time spots each time at individual voxels V1 [(1) is i...s. Here, (s) is the number of voxels on the surface marked)]. Thus, as the re-structure is limited by a main body device 10 to the specified surface or the capacity element V1, the electric density distribution of this re-structure can not be substantially distorted from the actual distribution.
