Thermal bus structure for a magnetic resonance imaging device

A magnetic resonance imaging device, comprising:

• a main magnet;
• a gradient system with at least one gradient coil;
• a cryocooler;
• a thermal bus structure;
• and
• an electromagnetic shield arranged between the gradient system and the main magnet,
• wherein the electromagnetic shield comprises a plurality of spaced shield elements confining the main magnet in a direction facing towards the gradient system and wherein the electromagnetic shield is configured to provide electromagnetic shielding of the main magnet from a magnetic field generated by the at least one gradient coil, and
• wherein the thermal bus structure comprises a plurality of thermal bus elements configured to provide a thermal connection between the plurality of spaced shield elements and a cold head of the cryocooler, at least two thermal bus elements of the plurality of thermal bus elements comprise different heat transfer properties to provide individualized temperature control of the plurality of spaced shield elements, and the plurality of thermal bus elements consist of solid thermal conductors.
