Cervicothoracic joint imaging coil component

Abstract

The invention relates to a cervicothoracic joint imaging coil component which comprises a cervicothoracic front piece, a nape base and carotid artery parts, wherein the cervicothoracic front piece isa semi-flexible structure, and the shape corresponds to the cervicothoracic front part of a standard human body; the upper surface of the nape base corresponds to the shape of the nape part of the standard human body; the lower surface of the nape base corresponds to a bed table; the carotid artery parts are movably arranged on two sides of the neck part of the nape base; coils are embedded in thecervicothoracic front piece, the nape base and the carotid artery parts; an insulating outer layer is arranged on the surface of each coil; when the cervicothoracic joint imaging coil works, the cervicothoracic front piece, the nape base and the carotid artery parts are fit with the surface of a subject.

Description

technical field [0001] The invention relates to the technical field of magnetic resonance imaging, in particular to a combined cervical and chest imaging coil assembly. Background technique [0002] The basic principle of magnetic resonance imaging is: some atoms in human tissue, such as hydrogen atoms, will generate magnetic moments due to spin motion, which can be regarded as small magnets, and these small magnets will produce directional arrangements under the action of a fixed static magnetic field And precess around the direction of the magnetic field at the same specific frequency; at this time, when a radio frequency pulse of the same frequency is applied, these hydrogen atoms absorb a certain amount of energy and generate resonance, and the spin direction is deflected under the action of the radio frequency pulse; after the radio frequency pulse disappears , these hydrogen atoms will return to their original state. During the recovery process, radio frequency energy ...

Problems solved by technology

[0004] At present, there are no neck-thorax coils with excellent performance on the market, because the shape of the human neck is relatively complex, and there are great differences between individuals.

Most commercial head-neck-thorax integrated coils are generally too large in order to be suitable for most subjects. Although the imaging range is large, there are not many channels in the neck, and some coil units are far away from human tissue, so the signal-to-noise ratio is not enough. high

Although the commercial carotid coil improves the signal-to-noise ratio to a certain extent, the imaging range is small, and it is often difficult to cooperate with other coils.
