ABSTRACT:
An MRI RF coil is shielded from extraneous noise sources using an extremely thin conductive shield interposed between the RF coil and the static magnetic structure of an MRI system. To control eddy currents induced in such conductor by the changing magnetic flux of MRI gradient coils, the RF shield conductor thickness is less than three skin depths at the MRI RF operating frequencies of the RF coil. Preferably, the RF shield conductor thickness is on the order of only one skin depth or less.
