Description

technical field [0001] The invention belongs to the technical field of magnetic resonance imaging, and in particular relates to a cooling system for radio frequency coils and magnetic resonance imaging equipment. Background technique [0002] Magnetic resonance imaging is a harmless medical imaging method, and it is one of the hot research fields in the field of biomedicine. Magnetic resonance imaging has great advantages and potential in disease diagnosis, precise positioning and disease prevention. The performance of magnetic resonance imaging is mainly determined by the magnetic field strength of the main magnetic field and the receiving performance of the radio frequency coil. However, the increase in the strength of the main magnetic field will also bring about the increase of the non-uniformity of the magnetic field, the increase of the instability of the magnet and the increase of the production cost of the magnet. Therefore, improving the performance of RF coils is...
