Conducting wires within the scanner may interact with the transmit field causing high shield currents and posing safety hazards. Closely spaced RF traps are used to mitigate common-mode currents. However, these bulky and rigid traps hinder the flexibility of the cable. We previously proposed caterpillar traps: a distributed system of smaller, flexible toroids covering the full length of the cable. Their potential to attenuate shield currents while being flexed was demonstrated. This work makes several improvements to the manufacturing process to reduce time and cost and improve usability. Furthermore, we present results from experiments to evaluate their performance and robustness.
