ABSTRACT:
A RF shield for an MRI system with a cylindrical geometry is disclosed. The RF shield is a plurality of panels with polyester on one side and copper cladding on the other side. The shingles include an adhesive so the shingles can be overlapped onto each other such that half of each shingle adheres to an adjacent shingle and the other half of the shingle adheres to the inside surface of the gradient coil assembly.
