Claim:
1. A fluid control system for use in a thermal therapy system, the fluid control system comprising: a treatment chamber for providing a therapeutic treatment to said patient with said thermal therapy system while imaging said patient with a magnetic imaging apparatus, said treatment chamber including a magnetic shielding wall with a penetration panel; a primary fluid circuit portion located in the treatment chamber and configured to circulate a sterile fluid, said primary fluid circuit portion comprising: a secondary fluid circuit portion configured to circulate a secondary fluid, said secondary fluid circuit portion comprising: a temperature sensor disposed between said first pump and said portion of the thermal therapy system, and configured to sense a temperature selected from the group consisting of a temperature of said sterile fluid and a temperature of a patient's tissue proximal to a position of said temperature sensor, and provide a corresponding temperature sensor output signal indicative of said temperature; and a temperature control circuit configured to receive said temperature sensor output signal, receive a reference signal indicative of a desired temperature setting, and provide said output control signal based on said temperature sensor output signal and said reference signal to control said chiller to maintain the temperature of said sterile fluid or the temperature of said patient's tissue proximal to the position of said temperature sensor substantially at or near the desired temperature setting.
