Abstract
Official abstract text for this publication.
A method of the present invention includes: a step of shimming an MRI superconducting magnet in consideration of the magnetic field atmosphere of a use place; a step of generating a rated magnetic field in the MRI superconducting magnet thus shimmed, under an environment in which the magnetic field atmosphere of the use place is realized; and a step of installing the MRI superconducting magnet in the use place after the step of generating the rated magnetic field. This reduces possibility of occurrence of quench and improves stability in the MRI superconducting magnet.
