Abstract
Embodiments relate to magnetic resonance imaging (MRI) radio frequency (RF) coil arrays having reduced coupling via hidden transmission lines. One example embodiment comprises a MRI RF coil array comprising: a first RF coil element coupled to a first output transmission cable (e.g., coaxial) that is configured to carry a first signal that is associated with the first RF coil element; a second RF coil element coupled to a second output transmission cable that is configured to carry a second signal that is associated with the second RF coil element, wherein the second RF coil element comprises a first portion of the first output transmission cable; and a first balun configured to reduce coupling associated with the first signal, wherein the first balun is arranged between the first RF coil element and the second RF coil element. Additional coil elements can be similarly combined in embodiments.
