Title:
SYSTEMS, ASSEMBLIES, AND METHODS OF SUPPRESSING MAGNET-GRADIENT INTERACTION IN MAGNETIC RESONANCE SYSTEMS
Document Type and Number:
Japanese Patent JP2023165622
Kind Code:
A
Abstract:
To provide a magnetic resonance (MR) system (10).SOLUTION: The system includes a main magnet assembly (12) configured to generate a polarizing magnetic field, a gradient coil assembly (22) including multiple gradient coils configured to apply at least one gradient magnetic field to the polarizing magnetic field, and a shield assembly (208) positioned between the main magnet assembly (12) and the gradient coil assembly (22). The shield assembly (208) includes an electrically conductive layer (304) fabricated with an electrically conductive material and defining multiple grooves (308) positioned through the electrically conductive layer (304), where the multiple grooves (308) block motional eddy currents caused by action of the polarizing magnetic field and of the at least one gradient magnetic field when the at least one gradient magnetic field is applied.SELECTED DRAWING: Figure 2A
