SYSTEMS AND METHODS FOR TOROIDAL TWINAX CABLE TRAP

The present invention provides systems and methods for toroidal twinax cable trap. Various methods and systems are provided for a flexible, lightweight, and low-cost radio frequency (RF) trap for use in a magnetic resonance imaging (MRI) system. In one example, a radio frequency (RF) trap assembly for use in a magnetic resonance imaging (MRI) system is provided, comprising a twinax wire assembly having a plurality of looped portions, each ones of the plurality of looped portions tangentially in contact with a shielded cable, and at least one support structure for substantially maintaining the shape of the plurality of looped portions, the support structure surrounding a portion of the shielded cable, wherein the twinax wire assembly is tuned to a frequency suitable for increasing the impedance of the shielded cable. 本发明题为用于环形屏蔽双线馈线电缆阱的系统和方法。本发明提供了用于在磁共振成像(MRI)系统中使用的柔性、轻质和低成本射频(RF)阱的各种方法和系统。在一个示例中，提供了在磁共振成像(MRI)系统中使用的射频(RF)阱组件，该RF阱组件包括：具有多个环形部分的屏蔽双线馈线导线组件，多个环形部分中的每个环形部分与屏蔽电缆切向接触；以及用于基本上维持多个环形部分的形状的至少一个支撑结构，该支撑
