A coil design termed as broadside-coupled loop (BCL) coil and based on the broadside-coupled split ring resonator (BC-SRR) is proposed as an alternative to a conventional loop design at 7T. The BCL coil has an inherent uniform current which assures the rotational symmetry of the radio-frequency field around the coil axis. A comparative analysis of the signal-to-noise ratio provided by BCL coils and conventional coils has been carried out by means of numerical simulations and experiments in a 7T whole body system.

:提出了一种称为宽边耦合环路(BCL)线圈并且基于宽边耦合裂环谐振器(BC-SRR)的线圈设计,作为7T常规环路设计的替代方案。 BCL线圈具有固有的均匀电流,可确保射频场围绕线圈轴的旋转对称性。通过在7T全身系统中进行数值模拟和实验,对BCL线圈和常规线圈提供的信噪比进行了比较分析。
