A gradient coil assembly for a magnetic resonance imaging device is disclosed. The gradient coil assembly comprises a cylindrical carrier with conductors forming three gradient coils associated with three orthogonal physical gradient axes. The cylindrical carrier comprises at least two radial through openings at different angular positions. At least one of the conductors runs through at least one area of the carrier located circumferentially between the through openings.

Techniques are disclosed relating to a cable connection unit for connection to a gradient coil unit, which includes at least one first electric conductor and one second electric conductor. The first electric conductor and the second electric conductor may be arranged at least partially next to one other, and be connected to one another via a load-carrying connection.

A magnetic resonance apparatus has a cylindrical gradient coil with an x-gradient coil and a y-gradient coil that are asymmetrical relative to the z-direction of a coordinate system, the z-direction extending along a longitudinal direction of a patient receptacle. Shim coils are provided that generate magnetic fields to homogenize the basic magnetic field, produced by a cylindrical basic field magnet, in an examination volume in the patient receptacle. At least some of the shim coils are asymmetrical relative to the z-direction to minimize coupling induction between the asymmetrical x-gradient coil and y-gradient coil and the asymmetrical shim coils.

Magnetic resonance device with an assembly having a recess, in which a gradient coil unit is attached with at least one attachment means, the attachment means having two members, between which an elastic element is disposed, only one of the members in each instance being in contact with either the gradient coil unit or the assembly, with the attachment means acting as an attachment means having no elastic element in a first attachment state, in which at least a minimum force presses the two members together, in that the two members have stop surfaces, which are in contact with each other due to the minimum force acting on the members compressed elastic element and with the attachment means acting as a spring unit in a second fixing state, in that the elastic element pushes the members apart in the event of forces smaller than the minimum force and causes the attachment means to be fixed in relation to the gradient coil unit and the assembly. This has the advantage that there is no loosening of the attachment means in particular even in the event of thermal fluctuations.
