Best Solution has assisted manufacturers of MRI scanner magnets using magneto-static finite element models. The models typically include the large superconducting magnet of the scanner and a soft iron shield which is normally included in the fabric of the building housing the scanner.
The permissible leakage fields are small for these installations, and we work alongside our customer to ensure that the shielding performance is satisfactory, and also that it is cost-effective. In addition, we can provide information on the forces acting on the superconducting coils as a result of the shield or other ferromagnetic objects in the vicinity.
