摘要： A magnetic resonance imaging system (402, 500) includes magnetic field gradient coils (516), a gradient coil power supply (320, 424, 518), a processor (540), and a chiller (308, 526) for providing the coolant to the gradient coils. The magnetic resonance imaging system further includes a memory (546) for storing machine executable instructions (580, 582, 584, 586, 588, 590, 592). The instructions cause the processor to receive (100, 200) a pulse sequence (550), to generate (102, 202) the chiller control signals using the pulse sequence and a chiller thermal model (582) of the gradient coils and the coolant reservoir, and to send (104, 206) the chiller control signals to the chiller. The chiller control signals cause the chiller to halt chilling at least a portion of the time when the gradient coil power supply supplies current to the magnetic field gradient coils.
