A method of determining a decoupling matrix of a decoupling system for an array of coils of a parallel transmission magnetic resonance imaging (MRI) system includes the steps of: obtaining impedance matrix data of the array of coils without the decoupling system; determining, based on the impedance matrix data of the array of coils, an objective function representative of a deviation from a decoupled operating condition of the array of coils in which the array of coils is decoupled via the decoupling system; and defining, using a processor, a decoupling matrix representative of a set of impedances of the decoupling system with an iterative procedure which optimizes elements of the decoupling matrix to minimize the objective function and reach the decoupled operating condition. |
