Abstract
A magnetic resonance imaging apparatus capable of suppressing noise caused by vibration of a gradient magnetic field coil and improving image quality includes a large number of ferromagnetic shims disposed in a large number of holes formed in a shim tray, and vibration dampers disposed in holes formed in the shim tray to reduce noise generated by vibration of a gradient magnetic field generating coil.
