Method for providing RF shielding for a nuclear magnetic resonance apparatus
First Claim
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.

Abstract
An apparatus and method for providing RF shielding for performing nuclear magnetic resonance (“NMR”) procedures, comprising a radio-opaque holder in combination with radio-opaque magnet components to form an RF shield around a patient undergoing an NMR procedure. In embodiments, a radio-opaque holder having a radio-opaque bottom portion and a radio-opaque canopy is adjoined to an NMR magnet having a radio-opaque cryostat and a radio-opaque service end cap to form an RF shield. A patient is placed on a patient support unit located in the holder bottom portion. The patient support unit, including the patient, is then inserted into the cavity of the NMR magnet and a canopy is placed on top of the bottom portion of the holder. An RF shield is thus created comprising the canopy, the bottom portion, the cryostat of the magnet, and an end cap on the service end of the magnet.
