Floating Solenoid Cable Trap.

In the current state of magnetic resonance imaging (MRI), transmission lines are vital in communicating with the transmitting and receiving networks. However, transmission lines, such as coaxial cables, operating at the radio frequencies (RF) used in MRI can be affected by common mode cable currents. These currents diminish received signals and put the patient at risk of RF burns. A common way to combat this issue is to implement cable traps on the transmission line(s). To effectively suppress cable currents and improve the ease of applying floating cable traps, a variation of a floating cable trap was created. The trap utilizes three LC circuits to provide an attenuation of -24 decibels (dB) at 127 MHz. The trap uses a custom 3D printed former that allows for straightforward construction and application onto a single RG-58 coaxial cable.
