Abstract

The embodiment of the invention provides a multi-channel radio frequency coil device an NMR imaging system. The multi-channel radio frequency coil device comprises at least two radio frequency coils which are arranged adjacently and used for generating nuclear magnetic resonance MR signals and/or receiving the nuclear magnetic resonance MR signals; and a decoupling loop arranged between the two adjacent radio frequency coils and is used for adjusting the induction current of the at least two radio frequency coils. The decoupling loop is arranged between the two adjacent radio frequency coils,so that the imaging integrity is improved on the premise of ensuring the decoupling performance is achieved.

Description

technical field [0001] Embodiments of the present invention relate to the field of magnetic resonance technology, and in particular to a multi-channel radio frequency coil device and a nuclear magnetic resonance imaging system. Background technique [0002] Aproton MRI plays an important role in the process of cell growth and can obtain important morphological and metabolic information. [0003] When using multi-channel RF coils for imaging, it is necessary to decouple the coils between adjacent channels, and the decoupling performance is crucial to the efficiency and parallel imaging performance of the coil array. At present, the coils between adjacent channels mainly solve the problem of electromagnetic coupling between coil channels through geometric overlapping technology (overlapping the operating magnetic field so that the mutual inductance of the two coils is zero). [0004] However, in the current way of decoupling, the overlapping parts between the coils of adjacen...
