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 ...
