Problems solved by technology

Due to the difference in human body size, and the temporomandibular joints are located on both sides of the cheeks, the temporomandibular coil needs to adjust the coil unit in multiple directions during scanning, which makes the positioning operation complicated, time-consuming and inefficient during scanning.

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] see Figure 1-9 , a radio frequency coil assembly for magnetic resonance imaging according to an embodiment of the present invention, which includes: a coil holder 10, a first coil 20a, a second coil 20b and a coil position adjustment mechanism 30, the first coil 20a, the second coil 20b It includes a housing 200 and coil units 201 and 202 arranged in the housing. The first coil 20a and the second coil 20b are arranged oppositely and connected to the coil position adjustment mechanism 30. The coil position adjustment mechanism is assembled with the coil support. The coil position The adjusting mechanism is used for adjusting the movement of the first coil and the second coil simultaneously, or for adjusting the movement of one of the first coil and the second coil.

[0033] The coil support 10 includes a crossbeam 101 extending in the horizontal...

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...
