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.
