Abstract:
Apparatus for providing vibration isolation between an MR imaging system and an associated nominally horizontal support surface, said apparatus comprising:a stiff platform of selectively substantial mass which is provided with a bearing surface and disposed to carry the weight of said MR imaging system; a number of vibration isolation elements positioned to support said platform and said MR imaging system upon said horizontal support surface in selected spaced apart relationship therewith, each of said isolation elements comprising an enclosure for air under pressure which is disposed to dampen vibrations applied thereto; a number of sensors selectively joined to said apparatus for detecting vibrations between said MR imaging system and said support surface, and for detecting degradation of MR imaging; and a pressure regulator coupled to respective isolation elements to maintain specified air pressure levels therein whereby vibrations between said MR imaging system and said support surface are dampened and MR imaging degradation is minimized.
