Abstract:
An apparatus for forming magnetic resonance images, said apparatus comprising:a gradient coil system that includes a carrier on which gradient coils are arranged, said gradient coil carrier being attached to a frame of the apparatus by way of connection means and defining a cylindrical axis, which connection means are constructed so as to reduce the transfer of mechanical vibrations that are produced by the gradient coil system, the connection means include a number of suspension elements, a first end of which is attached to the carrier whereas another end is connected to the frame of the apparatus, said connection means having a first mechanical stiffness in a first direction and a second, smaller stiffness in at least one direction that extends perpendicularly to the first direction, wherein a longitudinal direction of each of said suspension elements forms approximately a 45-degree angle with said cylindrical axis of said carrier in a stationary position, each of the first ends of the suspension elements being attached to a point of attachment of the carrier such that this point exhibits at least one low-vibration direction, and the connection direction between the first end and the second end of the suspension element being substantially coincident with the low-vibration direction of the point of attachment of the carrier.
