MRI ELECTRO MAGNETIC INTERFERENCE SHIELDING COIL FOR AN MRI SYSTEM

摘要

FIELD OF THE INVENTION The present invention relates to magnetic field adjustment systems and respective methods for use in magnetic resonance imaging (MRI) field generating assemblies. The magnetic field adjustment system includes a first magnetic field generating assembly and a further assembly. wherein the first magnetic field generating assembly is used to generate a first magnetic field required by the MRI; Said additional assembly comprising a switch and a current branch is used in cooperation with said first magnetic field generating assembly to generate a second magnetic field required by the MRI.
