A BALUN FOR USE IN MAGNETIC RESONANCE IMAGING (MRI) SYSTEMS AND AN MRI SYSTEM THAT EMPLOYS THE BALUN

A balun is provided that is suitable for use with miniature coaxial cables and that obviates the need to cut the cable in order to install the balun. A portion of each coaxial cable that extends fromthe RF receive coils to the RF receiver is wound multiple times around a device to form an inductor. The inductor may be used with or without a separate resonant circuit. If used with a separate resonant circuit, the inductor and the resonant circuit couple with one another to generate coupled impedance that provides common-mode noise suppression at the frequency of interest. If used without a separate resonant circuit, the inductor formed in the cable provides an inductance and the capacitance between the windings coupled with the inductance provides a series impedance that suppresses common-mode noise at the frequency of interest. 提供一种平衡转换器，其适用于与微型同轴线缆一起使用，并且不需要切割线缆以安装平衡转换器。从RF接收线圈延伸到RF接收器的每条同轴线缆的一部分围绕设备缠绕多次以形成电感器。电感器可以与或不与单独的谐振电路一起使用。如果与单独的谐振电路一起使用，则电感器和谐振电路彼此耦合以生成耦合阻抗，所述耦合阻抗提供在感兴趣的频率处的共模噪声抑制。如果不与单独的谐振电路一起使用，则在
