Abstract

The present disclosure relates to a gradient coil system (107, 207) for a magnetic resonance imaging, MRI, system (100). The gradient coil system (107, 207) comprises: a plurality of gradient coils (110A-C, 210A-C) for applying a gradient magnetic field to a target volume (108); at least one coolant tube (120A-C, 220A-C, 320A-C) per gradient coil (110A-C, 210A-C) for cooling the gradient coil (110A-C, 210A-C), the coolant tubes (120A-C, 220A-C, 320A-C) being connected to respective flow control devices (122A-C, 222A-C, 322A-C); a controller (124, 224, 324) coupled to the coolant tubes (120A-C,220A-C, 320A-C) configured to control each flow control device of the flow control devices (122A-C, 222A-C, 322A-C) for adjusting the flow of a coolant in the respective coolant tube (120A-C, 220A-C,320A-C), wherein the controller (124, 224, 324) is configured to control the flow control device (122A-C, 222A-C, 322A-C) on the basis of heat load caused by the respective gradient coil (110A-C, 210A-C).

Description

technical field [0001] The present invention relates to scanning imaging systems, in particular to cooling systems for gradient coil devices. Background technique [0002] Chillers utilizing water or a water and glycol mixture are commonly used to remove heat from the gradient coils of a magnetic resonance (MR) system. To minimize flow resistance, the cooling system consists of many parallel lines served by chillers. However, the gradient coils are usually not used with the same duty cycle and most of the cooling system's capacity is wasted. [0003] Japanese patent application JP H06-54819 relates to an open type magnet with opposing pole pieces of permanent magnets. The gradient coils are mounted on the corresponding pole heads. The gradient coils are liquid-cooled, and the cooling of the same pole head for the x gradient coils is piped in series with the cooling of the y gradient coils. The cooling of the gradient (x,y) coils at different pole tips is controlled separ...
