Abstract
A method of preparing a multi-channel coil, in particular for magnetic resonance imaging (MRI) or for a medical treatment device, wherein the multi-channel coil comprises at least two coil rows being axially arranged along a longitudinal direction (z), wherein each of the at least two coil rows comprises a plurality of coil elements being azimuthally distributed relative to the longitudinal direction (z), comprises the steps of a) electro-magnetic decoupling of the coil rows relative to each other, and b) minimizing a reflected power (Pref_row) individually of each of the coil rows. Furthermore, a method of operating a multi-channel coil, in particular for magnetic resonance imaging (MRI) or for a medical treatment device, and a multi-channel coil, which is prepared using to the above method are described.
