Magnetic resonance carotid plaque radiofrequency imaging coil

Abstract

The invention discloses a magnetic-resonance carotid plaque radiofrequency imaging coil, which is characterized by comprising a left coil shell body, a right coil shell body, a wiring box, a clamping frame and a cable, wherein a coil unit is arranged in each of the left coil shell body and the right coil shell body, each coil unit comprises a matrix loop formed by matching four groups of low-noise amplifying circuits, protective circuits, tuning circuits and decoupling circuits, and the shape of each coil unit and the corresponding matched circuits are different from one another through optimization, so as to adapt to irregular shapes of necks of human bodies. According to the magnetic-resonance carotid plaque radiofrequency imaging coil, the structures of the coil units adopt an optimal design, the magnetic-resonance carotid plaque radiofrequency imaging coil can be closely adhered to a detected portion when in use, the signal transmission efficiency is effectively improved, the signal attenuation is reduced, and the beneficial effects of high definition and high resolution are achieved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a magnetic resonance carotid artery plaque radio frequency imaging coil with novel design, flexible structure and good imaging effect. Background technique [0002] Magnetic resonance imaging is a biological magnetic nuclear spin imaging technology. The magnetic resonance system is generally composed of a magnet, a gradient system, a radio frequency system, a computer and peripheral equipment. Among them, the radio frequency coil is an important part of the radio frequency system. The radio frequency pulse with the same frequency as exciting the hydrogen protons in the human tissue precesses, and the main magnetic field generated by the radio frequency pulse and the magnet makes the precessing hydrogen protons in the human tissue precess to generate a magnetic resonance radio frequency signal, which is processed by a computer and imaged. Precession is the result of the ...

AI Technical Summary

Problems solved by technology

However, the carotid artery coils in the prior art are mostly open structures or fixed embedded external structures, which have poor flexibility. Regardless of the size of the neck, they are all in the same open cavity, so the carotid artery coils are mostly in larger sizes. , A wide range of multi-channel design presentation, limited to the use of the neck, and cannot better fit the detected parts, affecting the clarity and resolution of neck imaging of different sizes, etc.
