The invention relates to a magnetic resonance imaging (MRI) apparatus (1)
comprising a main magnetic system (2) for generating a main magnetic
field in an examination volume (7) which is enclosed by the main magnetic
system (2). The MRI apparatus also comprises a magnetic gradient coil
system (3) comprising gradient coils. The gradient coil system (3) is
accommodated between the main magnetic system and the examination volume
in order to generate gradients of the main magnetic field. The MRI
apparatus also comprises a vacuum space (13). According to the invention,
the gradient coil system only partly adjoins the vacuum space, that is,
by way of its side which faces the examination volume. Thus, the
examination volume is effectively shielded from acoustic vibrations
caused by the gradient coil system in operation, while, in a specific
embodiment, the end sides (22) of the gradient coil system are available
for electrical and mechanical connections outside the vacuum space.
