Abstract
An MRI RF transmit system uses a plurality of RF transmit coils, each being driven with separately controllable RF magnitude and phase. The magnitude and phase of each coil drive are separately and independently controlled so that the RF transmit coils act as if they are decoupled from each other. The controlled magnitude and phase values may be based on empirically derived information relating to self and mutual coupling of RF transmit coils.
