Abstract
Embodiments relate to MRI coils and arrays comprising transmission lines to enforce periodic conditions. An example embodiment comprises a MRI RF coil array comprising: a plurality of assemblies, wherein each assembly of the plurality of assemblies comprises: a two-port device of that assembly, wherein the two-port device of that assembly is similar to the two-port device of each other assembly of the plurality of assemblies, and wherein the two-port device of that assembly comprises at least one associated inductor configured to, in a Tx mode, generate at least a portion of a B1 field; and a transmission line of that assembly, wherein a length of the transmission line of that assembly can be similar to a length of the transmission line of each other assembly of the plurality of assemblies, wherein the plurality of assemblies are connected together in a loop.
