Abstract:
1. A method for adjusting an MRI superconducting magnet before installation thereof in a use place, comprising the steps of: shimming said MRI superconducting magnet in consideration of a magnetic field atmosphere of said use place; generating a rated magnetic field in said MRI superconducting magnet thus shimmed, under an environment in which said magnetic field atmosphere of said use place is realized; and installing said MRI superconducting magnet in said use place after the step of generating said rated magnetic field, wherein: a magnetic member is disposed around said MRI superconducting magnet to realize said magnetic field atmosphere of said use place, and said magnetic member exerts, to said MRI superconducting magnet generating said rated magnetic field, electromagnetic force equivalent to electromagnetic force exerted to said MRI superconducting magnet generating said rated magnetic field in said magnetic field atmosphere of said use place.
