One of the critical problems coil designer confront is the parasitic current induced on the cables during transmit phase of the MRI sequence. During receive phase cables must not couple to the multiple coil elements, otherwise shading, oscillations and heating could occur. Typical method of reducing the current on cables is by utilizing cable baluns. In this work we try to accommodate the well-known quarter wave balun to the low frequencies without adding length to the signal transmission line and without adding any lumped circuit components.
