Radio frequency cable assembly and magnetic resonance imaging system

Abstract

The invention provides a radio frequency cable assembly for a magnetic resonance imaging system and the magnetic resonance imaging system. The radio frequency cable assembly comprises a cable, a wave trap and a limiting and fixing unit, the wave trap is installed on the cable in a sliding mode, and the limiting and fixing unit comprises a sleeving part and a matching part which are relatively fixed; the sleeving part sleeves the wave trap, and the matching part has a locking state and a sliding state which can be converted; the matching part fixedly clamps the cable in the locking state so that the cable cannot slide relative to the sleeving part, and the matching part and the cable can slide relative to each other in the sliding state. The defect that a traditional radio frequency cable assembly needs to be wound with a cable is overcome, and the step of assembling the wave trap and the cable is simplified. When radio frequency debugging is carried out, the matching part is switched to a sliding state, so that fixation between the matching part and the cable can be relieved, and the wave trap can be driven to slide on the cable; and after radio frequency debugging is completed, the matching part is switched to a locking state, so that the matching part and the cable can be fixed again, and the wave trap is fixed on the cable.

Description

technical field [0001] The invention relates to the technical field of magnetic resonance imaging, in particular to a radio frequency cable assembly and a magnetic resonance imaging system. Background technique [0002] At present, radio frequency cable assemblies are commonly used in magnetic resonance imaging systems, and the radio frequency cable assemblies include cables and wave traps. In practical applications, it is necessary to perform radio frequency debugging on the radio frequency cable assembly according to the field strength of the imaging system and the radio frequency coil. Traditional radio frequency cable assemblies usually use a structure in which the cable is wound and the wave trap is fixed on the cable. This structure is not only inconvenient to assemble the cable and the wave trap, but also brings difficulty to radio frequency debugging. Contents of the invention [0003] In view of this, the present invention provides a radio frequency cable assembl...
