Abstract
A gradient coil system for a magnetic resonance imaging system includes a plurality of gradient coils for applying a gradient magnetic field to a target volume; at least one coolant tube per gradient coil for cooling the gradient coil (110A-C, 210A-C). The coolant tubes are connected to respective flow control devices and a controller, which is configured to control each flow control device of the flow control devices for adjusting the flow of a coolant in the respective coolant tube. The controller is configured to control the flow control device on the basis of heat load caused by the respective gradient coil.
