Coil placement method of the static magnetic field coil device static magnetic field coil device, and nuclear magnetic resonance imaging apparatus

摘要

Providing a nuclear magnetic resonance imaging apparatus using the static magnetic field coil unit and a static magnetic field coil device with good uniformity of the static magnetic field, while avoiding an increase in cost (MRI apparatus). Static magnetic field coil apparatus comprising a plurality of coils which are arranged coaxially to generate a static magnetic field a predetermined area (8) in a (2a) and a (2), the plurality of coils to (2a), the coil ( plane of symmetry (11), the coil (2a) are arranged in plane symmetry, the coils at the position is far from (11) the symmetry plane to the extent (12a) a vertical plane (10) central axis 2a), The long and the axial direction, and wide in the radial direction.
