Abstract
Apparatus which provides a barrier for vibrational energy between an MR imaging system and an associated horizontal support surface includes a stiff platform of substantial mass, which is disposed to carry the entire weight of the MR imaging system. The apparatus further includes a number of vibration isolation elements positioned to support the platform and the MR imaging system upon the horizontal support surface. Each of the isolation elements comprises an enclosure containing pressurized air which is disposed to dampen vibrations, in order to oppose the transmission of vibrations between the platform and the support surface. An air pressure regulator is coupled to respective isolation elements to maintain specified air pressure levels therein, in order to support the platform in selected spaced-apart orientation with respect to the horizontal support surface.
