Abstract: A RF shield (10), for use adjacent a portion of a patient's body during a magnetic resonance examination by magnetic resonance examination apparatus, includes an electrically and thermally conductive layer (20) having a pair of opposed surfaces, and a pair of electrically and thermally insulative layers (22 and 24). One of the insulative layers is disposed adjacent one of the opposed surfaces for positioning intermediate the conductive layer and the patient's body portion to insulate the patient's body from the conductive layer, and the other of the insulative layers is disposed adjacent the other of the opposed surfaces for positioning intermediate the conductive layer and the magnetic resonance examination apparatus to insulate the magnetic resonance apparatus from the conductive layer.
