초록

The shield effects of the actively shielded superconducting magnet systems for MRI were investigated. The magnetic field was calculated by FEM considering the winding error and the homogeneity of the magnetic field at the 30cm DSV was presented. The 5 gauss stray field line was restricted within 5m form the magnet center.
