Patent ID: 7307421

Claim:
A magnetic resonance imaging apparatus comprising a pair of static magnetic field generating sources opposingly disposed on both sides of an imaging space and gradient magnetic field generating part disposed on the imaging space side of each static magnetic field generating source for applying a gradient magnetic field to the imaging space, wherein the static magnetic field generating sources each comprise a magnetic field generating coil and a closed vessel enclosing the magnetic field generating coil inside, the gradient magnetic field generating part is supported on a face of the closed vessel on the imaging space side, at least one of the closed vessel has a rigid structure for preventing transmission of vibration generated by the gradient magnetic field generating part to other members via the closed vessel, the rigid structure has a rigid reinforcing member provided on the side confronting the face on the imaging space side of the closed vessel, the rigid structure has at least one connecting part connecting a face on the imaging space side and a face confronting the face of the closed vessel inside the closed vessel, the rigid reinforcing member is fixed on the face confronting the face on the imaging space side of the closed vessel, and the rigid reinforcing member comprises at least one of a plate member and a grid member.
