Mri system

Abstract

An MRI system includes a static magnetic field magnet configured to determine an MR frequency for imaging and generate a first static magnetic field be applied to an object during imaging; a pre-polarizing magnet configured to polarize nuclear spin of the object prior to imaging of the object and generate a second static magnetic field, application of which is stopped during imaging of the object; at least one first shield configured to block a leakage magnetic field of the first static magnetic field, the first shield being provided in a region opposite to an imaging region of the object with respect to the static magnetic field magnet; and at least one second shield configured to block a leakage magnetic field of the second static magnetic field, the second shield being provided in a region opposite to the imaging region with respect to the pre-polarizing magnet.
