The conventional decoupling technique of coil overlap leads to stringent constrains on how the elements are placed. This fixed overlap may not always be appropriate for parallel spatial encoding. Some alternative decoupling methods are to insert capacitors or LC circuit networks between coils to minimize their mutual coupling. To clearly illustrate the LC decoupling circuit, the technique by inserting decoupling-capacitors (Cd) or decoupling-inductors (Ld) for isolation arbitrarily placed coils was studied. Also we compare the decoupling performance by using Cd and Ld at variable magnetic fields.
