MAGNETIC FIELD STABILIZATION METHOD, MAGNETIC FIELD GENERATING APPARATUS AND MAGNETIC RESONANCE IMAGING APPARATUS.

摘要

In order to provide a magnetic field stabilization method, magnetic field generating apparatus and magnetic resonance imaging apparatus that is not affected by the temperature distribution in an installation space, in stabilizing a magnetic field of a magnetic field generating apparatus 2 having a pair of permanent magnets facing each other with a space interposed and yokes constituting a magnetic circuit for the permanent magnets, heat quantities to be applied to a plurality of positions are individually controlled (172, 174) based on the temperatures detected at a plurality of positions 154, 158 on the yoke to stabilize the respective temperatures at the plurality of positions.
