Faraday have experienced technicians who can perform testing on your existing Faraday cage to determine its shielding effectiveness. Following testing, Faraday prepare a report showing the results and compare these against MRI vendor specifications to determine whether the cage is still performing as it should.
If your old Faraday cage is not performing to specification, Faraday can make recommendations and provide options for repair or replacement of your shield or certain components.
Faraday recommend this testing if you are thinking of changing over your existing MRI system. It helps to know if your Faraday cage needs repair so arrangements can be made whilst the system is being replaced.
