Design of a compact planar GC for high field open MRI using the computational tool DUCAS was done. The DUCAS can treat arbitral sheet currents and was applied on the GC design. The designed GC is a ASGC. It has umbrella shaped shield coil and plane main coil with direct connection between them. These two characteristics made the GC size compact and the leakage field weak. Then we conclude this ASGC can be used as planar ASGC for high-field open MRI.
