Phased-array coils are extensively employed in Magnetic Resonance (MR) as transmitter and receiver radiofrequency (RF) coils due to their large field-of-view (FOV) and their high signal-to-noise ratio (SNR). Array elements have to be geometrically decoupled for mutual coupling minimization, to achieve coil performance maximization. This paper proposes an analytical method for the mutual inductance calculation between two square loops constituting a 2-element phased-array coil in dependence on the conductor cross-sectional geometry (flat strip and circular wire). Simulation accuracy was evaluated with workbench experimental measurements performed at 21 MHz frequency on two home-built array square coils.

具有带状和线状导体的磁共振二元相控阵方形线圈中的互感

由于相控阵线圈的大视场 (FOV) 和高信噪比 (SNR)，相控阵线圈在磁共振 (MR) 中被广泛用作发射器和接收器射频 (RF) 线圈。阵列元件必须在几何上解耦以最小化相互耦合，以实现线圈性能最大化。本文提出了一种分析方法，用于根据导体横截面几何形状（扁带和圆线）构成一个 2 元相控阵线圈的两个方形回路之间的互感计算。仿真精度通过工作台实验测量在 21 MHz 频率下对两个自制阵列方形线圈进行评估。
