A gradient coil assembly of a magnetic resonance imaging system includes at least one gradient coil, a cooling arrangement for cooling the gradient coil, and an RF shield. The cooling arrangement includes at least one cooling tube that is configured to transport a cooling fluid and which is disposed on and in thermal contact with the gradient coil, wherein the assembly further comprises a thermal connector arrangement with at least one of a first thermal connector disposed between the RF shield and the at least one cooling tube, which provides a radially extending connection between the RF shield and the at least one cooling tube.

Cooling a gradient coil of a magnetic resonance imaging system

A gradient coil assembly () for use in a Magnetic Resonance Imaging (MRI) system includes primary coils (), shield coils () and a supporting structure () arranged between the primary coils () and the shield coils (). The supporting structure () includes at least a supporting element () including a first end face () and at least a first recess () with an opening () in the first end face (). The first recess () extends in a longitudinal direction () of the supporting element () forming a tray for receiving a passive shim bar.

Supporting structure for a gradient coil assembly of a MRI

A magnet assembly is provided. The magnet assembly comprises a magnet configured to generate a magnetic field and an iron shield configured to shield the magnet. The magnet assembly further comprises one or more positive temperature coefficient heaters disposed on the iron shield and configured to stabilize temperature of the iron shield. An iron shield assembly and a method for temperature control of the magnet assembly are also presented.
