ABSTRACT:
A plurality of magnetic field measurement units are arranged near a patient, a current source distribution and/or a current dipole in the patient are estimated on the basis of plurality of magnetic field distribution data measured by the magnetic field measurement units within a predetermined period of time. In particular, the current distribution and the current dipole at the desired time within the predetermined period of time are estimated by using spatiotemporal magnetic field distribution data measured by the plurality of magnetic field measurement units within the predetermined period of time and correlation information of the spatiotemporal magnetic distribution data. The current distribution and the current dipole are estimated by using cross-correlation information of noise data measured by the plurality of magnetic field measurement units.
