The present invention relates to a magnetic resonance receiving coil and a magnetic resonance receiving coil assembly, comprising a first conductor bent along a set direction to form a loop, and the first conductor has opposite first ends and second ends; one or more A plurality of conductor layers are arranged in parallel with the first conductor, and a plurality of the conductor layers respectively extend along the bending direction of the first conductor and can be electrically coupled with the first conductor. The above-mentioned magnetic resonance receiving coil and magnetic resonance receiving coil assembly adopt two conductors to form a transmission line structure, and openings with different positions are set on the two conductors to achieve a resonance state, so that the current in the transmission line flows between the two conductors, increasing etc. Efficient transmission line length, the size of the coil can be reduced at the same resonance frequency, the cost is reduced, the use is more convenient, and the adaptability is stronger.
Description
technical field [0001] The invention relates to the technical field of magnetic resonance imaging, in particular to a magnetic resonance receiving coil and a magnetic resonance receiving coil assembly. Background technique [0002] Existing magnetic resonance receiving coils usually adopt a phased array design, wherein each array unit is a loop coil. Toroids are usually made of copper foil or wire, and arrays of these toroids can be mounted on a carrier made of rigid or flexible printed circuit boards. In order to form resonance, a lumped capacitor needs to be connected in series with the coil. However, in the resonant state, there is a local electric field at both ends of the capacitor. This electric field is coupled with the scanned load, resulting in dielectric loss and frequency shift, which ultimately affects the signal-to-noise of the received image. Compare. [0003] In order to solve the above problems, the solution in the prior art is to use multiple capacitors ev...
