Embodiment Construction

[0059]In order to make the purpose, technical solutions, and advantages of this application clearer, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the application, and not used to limit the application.

[0060]At present, in the magnetic resonance signal receiving technology, when the coil control module controls the receiving coil for signal reception, it usually outputs a pulse-like large current through reciprocating output current to control the receiving coil inside the receiving chain module. However, during the implementation of the above technology, the internal circuit of the coil control module will generate heat, which will cause the temperature fluctuation of the coil control module to change greatly, which will affect the temperature of the receiving chain module, thereby affecting the stability of the rece...
