PROBLEM TO BE SOLVED: To more accurately specify the relative pisitional relation of a testee body to a flux meter. SOLUTION: A current supply unit 11 simultaneously supplies the AC currents of different frequencies to respective plural oscillation coils C1-Cn stuck to the testee body M at a prescribed flow rate so as to make magnetic field strength generated for the respective oscillation coils C1-Cn measured by the flux meters S1-Sm be almost same. Magnetic fields simultaneously generated from the respective oscillation coils by the supplied current are detected by the flux meters S1-Sm, passed through a data gathering unit 2 and frequency- analyzed in a magnetic field discrimination part 3 and the magnetic field strength due to the respective oscillation coils C1-Cn is discriminated for the respective flux meters S1-Sm. Based on magnetic field data discriminated for the respective oscillation coils C1-Cn, in a magnetic field analysis part 4, the relative positions of the respective oscillation coils C1-Cn to the flux meters S1-Sm are calculated. Based on the position information, information for indicating a separately measured living body activity current source is displayed at a current source generation position on MRI images. |
