Abstract

The present disclosure relates to a magnetic resonance imaging device and shimming methods on the magnetic resonance imaging device. The magnetic resonance imaging device includes a main magnet, gradient coils, a vacuum enclosure, and a shimming conduit. The vacuum enclosure is configured to house at least part of the shimming conduit. The vacuum enclosure and at least part of the shimming conduit defines a hermetically sealed space configured to house the gradient coils. The shimming conduit has at least one opening configured to allow for access to an interior of the shimming conduit. The interior of the shimming conduit is hermetically insulated from the hermetically sealed space.
