DETAILED DESCRIPTION

In magnetic resonance imaging (MRI) system, radiofrequency generated from a magnetic resonance (MR) coil affect function of MRI system and that of acquired images.

Therefore, there exists a need for an efficient technique that covers or shields radiofrequency by the MR coil.

The invention includes a technique to shield radiofrequency (RF) generated by a magnetic resonance (MR) coil in a magnetic resonance imaging (MRI) system. The technique includes carbon fibers as conductive material. Reinforced carbon fibers are woven in a meshed structure or glued together with a conductive adhesive. The carbon fiber mesh can block RF when the distance between fibers is in millimeter to micrometer range.  FIGURE 1 depicts carbon RF shield for the MRI system. As illustrated in FIGURE 1, RF fibers shield includes carbon fiber layer followed by conductive adhesive layer on both its sides. On one of the sides gradient coil is configured after the conductive adhesive layer. On the other side reinforced glass fiber layer is configured after the conductive adhesive layer and further followed by bo...
