Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a radio frequency coil system applied to rotating magnetic resonance. Background technique [0002] In modern medical technology, magnetic resonance imaging system has been a commonly used medical equipment. As an integral part of the system, the radio frequency coil has a great influence on the performance of the magnetic resonance imaging system. The existing designs of RF coils mainly include orthogonal plate type, straight wire type and other structures. In the above structure, all coils are fixed on the magnet of the magnetic resonance system. According to physical principles, RF coils need a good RF environment. In order to ensure that the resonant frequency of its coil will not change, it is a fixed radio frequency coil. [0003] With the continuous advancement of medical technology, fixed radio frequency coils can no longer meet the requirements, and sometimes m...
