Beschreibung
Zusammenfassung:	An apparatus for controlling the temperature of a warm bore of a superconducting magnet in a magnetic resonance imaging (MRI) includes a plurality of warm bore thermal sensors positioned on a surface of the warm bore and a plurality of heater elements positioned on the surface of the warm bore. A heater element thermal sensor is coupled to each of the plurality of heater elements and configured to monitor the temperature of the corresponding heater element. A controller is coupled to the plurality of warm bore thermal sensors and the plurality of heater element thermal sensors. The controller is configured to control each of the plurality of heater elements to maintain a predetermined temperature of the warm bore.
