Abstract
A vibration quenching substrate which effectively isolates diagnostic equipment such as magnetic resonance imaging devices from image degrading vibrations. The substrate comprises numerous layers including a base layer, an elastomeric layer, and an inertia base layer which free-floats on the elastomeric layer. Importantly, the elastomeric layer is free of any rigid connection to either the base or inertia base layers.
Claims24
A vibration reducing substrate for a medical diagnostic device, the substrate comprising:
- an inertia base layer which is adapted to support said medical diagnostic device;
- an elastomeric layer, said inertia base layer freely floating on said elastomeric layer so that said inertia base layer is free of any direct connection to a surrounding floor;
- and
- a base layer, said elastomeric layer residing on said base layer, and wherein said base layer is reinforced with non-ferrous or non magnetic rebar.
A substrate to reduce vibration transmissions from surrounding surfaces to a medical diagnostic device, said substrate comprising:
- a base layer, wherein said base layer includes a radio frequency (RF) shield layer extending through the length and width of said base layer;
- an elastomeric layer located on said base layer;
- and
- an inertia base layer residing on said elastomeric layer, said inertia base layer adapted to support a medical diagnostic device, said elastomeric layer being free of a fixed connection to said base layer and said inertia base layer.
A vibration reducing substrate, comprising:
- an inertia base layer which is adapted to support a device;
- a plurality of elastomeric isolators;
- and
- a base layer, said plurality of isolators each having a first surface contacting the inertia base layer and a second opposite surface residing on the base layer, wherein each isolator is spaced a predetermined distance and free of any direct elastomeric connection from the remaining isolators, wherein said isolators are free of any fixed connection to said base layer and said inertia base layer wherein said inertia base layer is free of any direct connection to a surrounding floor, and wherein the base layer includes non-magnetic rebar.
