Abstract
An apparatus for cooling a gradient coil assembly of a magnetic resonance imaging (MRI) system and for controlling a temperature of a magnet warm bore is provided. The gradient coil assembly includes an inner gradient coil assembly and an outer gradient coil assembly. A first cooling circuit is provided that has a cooling tube positioned at a distance from the inner gradient coil assembly. The cooling tube of the first cooling circuit is configured to transport a first coolant having a first temperature. A second cooling circuit is provided that has a cooling tube positioned at a distance from the outer gradient coil assembly. The cooling tube of the second cooling circuit is configured to transport a second coolant having a second temperature. The apparatus also includes a controller coupled to the first cooling circuit and the second cooling circuit. The controller is configured to independently control the first temperature of the first coolant and the second temperature of the second coolant.
