High-magnetic field MRI system within a housing and a method of operating an MRI system within a housing

摘要

An MRI system is housed within a housing that is provided with a set of deployable barriers that are attachable to the housing. The magnet in the MRI system may be operated at a first magnetic field intensity, such that the magnetic field outside of the housing remains below a safety limit when the barriers are not deployed. The magnet in the MRI system may be operated at a second magnetic field intensity, higher than the first, when the barriers are deployed, such that the magnetic field outside of the barriers remains below the safety limit.
