PURPOSE: To permit the high speed imaging and suppress the generated noise and improve the linearity characteristic of an inclined magnetic field by arranging a conductor on the first and second coil planes according to the wiring pattern based on the final electric current distribution function obtained through the repetitive method.
CONSTITUTION: Inside a magnet bore 1, an inclined magnetic field coil 2, body part antenna coil 3, local inclined magnetic field coil 4 in parallel flat plate form are arranged inside in succession from the outside. As for the local inclined magnetic field coil, a conductor is arranged on the both coil planes according to the wiring pattern based on the final electric current distribution function which is obtained through the repetitive method. The local incline magnetic field coil is formed by nipping an inspected body by the local part of an inspected body 5 inside the body part antenna coil, and since size is small and the coil is separated from the magnetic bore, the eddy current loss is reduced, and the high inclined magnetic field can be generated, and the high speed imaging is permitted. Further, the increase of the installation cost and operation cost and the generation of large sound can be suppressed. Further, the linearity characteristic of the generated inclined magnetic field is improved drastically by the wiring pattern on the basis of the final electric current distribution function obtained by the repetitive method.
