Abstract
A system for isolating vibration and reducing acoustic noise in the RF coil of an MR imaging apparatus is presented. The system positions an RF conductor in its operative position proximate to an RF support form. The RF conductor is sandwiched between a vibration decoupling layer and a mass loading layer. The vibration decoupling layer is affixed to the RF support form so that the vibration decoupling layer is positioned between the RF conduit and the RF support form while the mass loading layer is located exterior of the RF conductor. By this arrangement, the acoustic energy is decoupled from the RF support form by the vibration decoupling layer while the vibration is reduced by the mass loading layer located exterior of the RF conductor.
