Abstract

PURPOSE:To enhance leaked magnetic field shield effect, by forming the title magnetic shield system inclusive of a shield material having a high saturation flux density characteristic. CONSTITUTION:An MRI apparatus 1 has a magnet stand 1a equipped with various coils and a bed 1b for mounting an examinee, and the whole thereof is surrounded by a shield material 2. Herein, as the shield material 2, an alloy having a high saturation flux density characteristic is used and, as this alloy, an Fe-Co alloy is designated as apparent from a Slater-Pauling curve and the saturation flux density thereof is highest. Therefore, when this Fe-Co alloy is used, the flux density B to a high magnetic field becomes high and shield effect is enhanced.
