To avoid interference from external magnetic fields, MRI systems are installed in magnetically shielded rooms. Although generally very efficient, variable background fields can be problematic, and the cause can be very obscure, such as the return current of a train passing many kilometers away. Such situations often call for “active“ shieldingIn magnetics, this refers to shielding the outside world from a magnetic field generated by a magnet, or vice versa.... More systems that monitorSee Control. More the environmental fields and compensate for them in real-time with a set of coils built into the walls.

More systems are the perfect tools to track down such problems. They allow ultra-precise, long term monitoring of the magnetic field exactly where it counts – in the imaging area. They can also be used to verify – and certify! – the performance of active shieldingIn magnetics, this refers to shielding the outside world from a magnetic field generated by a magnet, or vice versa....
