1. A method of providing RF shielding for a nuclear magnetic resonance (NMR) apparatus comprising a substantially cylindrical NMR magnet configured for an NMR procedure, comprising:

  • placing a patient on a radio-opaque holder having a rigid surface defining an opening at a magnet end that substantially matches an opening defined by a patient-end surface of the NMR magnet;

    adjoining the rigid surface of the holder to the patient-end surface of the NMR magnet so that the rigid surface abuts against the patient-end surface and electrically couples to a radio-opaque portion of a cryostat of the NMR magnet, the NMR magnet comprising a service end adjoined to a radio-opaque covering that is electrically coupled to the cryostat, thereby forminga substantially complete and substantially continuous RF shield operative to prevent RF signals from interfering with an NMR procedure conducted using the NMR magnet.
