Abstract
In a method for cooling an MRI apparatus, and an MRI apparatus, the MRI apparatus has a magnet, a primary cooling device and a secondary cooling device, and a magnet controller, the primary cooling device being in contact with the magnet and the secondary cooling device separately. The magnet controller continuously monitors a pressure of the magnet, and turns off the secondary cooling device if the pressure is greater than or equal to a first preset pressure, of less than a second preset pressure and in a rising state. The present invention can save electricity, and since the duration of use of the secondary cooling device is also reduced, the lifespan of the secondary cooling device is prolonged, saving costs.

A method performed by a magnetic resonance imaging (MRI) apparatus for cooling the MR apparatus, wherein the MRI apparatus comprises a magnet, a primary cooling device, a secondary cooling device, and a pressure sensor that detects a pressure of the magnet, the primary cooling device being in contact with the magnet and the secondary cooling device separately, the method comprising:
- continuously monitoring the pressure of the magnet;
- turning off the secondary cooling device if the pressure is greater than or equal to a first preset pressure, less than a second preset pressure, and in a rising state between the first preset pressure and the second preset pressure.
A magnetic resonance imaging (MRI) apparatus, comprising:
- a magnet;
- a primary cooling device that is in contact with the magnet;
- a secondary cooling device that is in contact with the primary cooling device;
- a pressure sensor that detects a pressure of the magnet;
- a magnet controller configured to continuously monitor the pressure of the magnet, and to judge the pressure, and if the pressure is greater than or equal to a first preset pressure, less than a second preset pressure, and in a rising state between the first preset pressure and the second preset pressure, then to turn off the secondary cooling device.
