Abstract

The invention discloses a radio frequency coil assembly for magnetic resonance imaging. The radio frequency coil assembly for magnetic resonance imaging comprises a coil support, a first coil, a second coil and a coil position adjusting mechanism, wherein the first coil and the second coil comprise casings and coil units arranged in the casings, the first coil and the second coil are oppositely arranged and are connected with the coil position adjusting mechanism, the coil position adjusting mechanism is assembled with the coil support, and the coil position adjusting mechanism is used for adjusting the first coil and the second coil to simultaneously move or one of the first coil and the second coil to move. The radio frequency coil assembly is advantaged in that symmetric design is employed, the coil position adjusting mechanism is employed to reduce the swing position during scanning to three steps, operation of a technician is simplified, and swing efficiency is improved.

Description

[0001] 【Technical field】 [0002] The invention relates to magnetic resonance imaging technology, in particular to a radio frequency coil for magnetic resonance imaging. [0003] 【Background technique】 [0004] The basic principle of magnetic resonance imaging is: some atoms containing a single number of protons in human tissue, such as hydrogen atoms, can spin and generate magnetic moments, which can be regarded as some small magnets. Under normal conditions, the spin direction of these small magnets The arrangement is irregular, but under the action of a fixed static magnetic field, there will be a directional arrangement; at this time, when a radio frequency pulse with the same frequency as the static magnetic field is applied, these hydrogen atoms absorb a certain amount of energy and resonate, and the spin direction is under the action of the radio frequency pulse The deflection occurs and the arrangement is regular, that is, the phenomenon of magnetic resonance occurs; af...
