Abstract:
An apparatus for controlling a temperature of a warm bore of a superconducting magnet in a magnetic resonance imaging (MRI) system includes a cooling tube that is mounted on a surface of the warm bore and is configured to transport a coolant. A chiller is coupled to the cooling tube and is configured to provide the coolant to the cooling tube. A controller is coupled to the chiller and is configured to provide a control signal to the chiller to control a temperature of the coolant.
