GRADIENT COIL SUPPORTING IMPLEMENT AND MAGNETIC RESONANCE IMAGING APPARATUS

摘要

In one embodiment, a gradient coil supporting implement includes three bearings and a mounting main body. At least one of the three bearings is a spherical bearing. Shafts of these bearings are fixed to a static magnetic field magnet of an MRI apparatus. One end side of the mounting main body is fixed to an outer periphery side of an end face of the static magnetic field magnet, at one position via one of the bearings. The other end side of the mounting main body is fixed to an inner periphery side of the end face of the static magnetic field magnet, at two positions via the other two bearings. The mounting main body supports the gradient magnetic field coil unit (installed inside the static magnetic field magnet) in the horizontal direction by being partially made in contact with the gradient magnetic field coil unit.
