Abstract

The invention discloses a magnetic resonance radio frequency receiving coil with a coil unit isolating function. The magnetic resonance radio frequency receiving coil comprises at least three coil units. The coil units include at least one coupling coil assembly composed of two coil units. A public isolation adjusting circuit is arranged between the two coil units of the coupling coil assembly and connected into the two coil units of the coupling coil assembly in series. The isolation adjusting circuit comprises a capacitor and a first electric inductor which are connected in series. The first electric inductor is coupled with an electric inductor of at least one coil unit except the coupling coil assembly in a mutual inductance mode. The magnetic resonance radio frequency receiving coil has the advantages that the number of the applied electric inductors is small, the structure is simple and compact, components and parts are arranged conveniently and fast, the signal to noise ratio of the coil is low, and the coil is not prone to oscillation and is convenient and easy to design and use.

Description

technical field [0001] The invention relates to the field of magnetic resonance imaging, in particular to a magnetic resonance radio frequency receiving coil with a coil unit isolation function. Background technique [0002] Magnetic resonance imaging (MRI) is a very important part of modern medical imaging, with the characteristics of non-invasiveness and no ionizing radiation. The radio frequency receiving coil is an important part of the magnetic resonance system. The performance of the magnetic resonance radio frequency receiving coil directly determines the imaging quality of the magnetic resonance system, so it is called the "eye" of the magnetic resonance system. [0003] In order to obtain better image quality, the number of channels of the magnetic resonance radio frequency receiving coil is increasing. In this case, it becomes more and more important to eliminate the coupling between channels and achieve good isolation. To this end, people have proposed a variety...
