Abstract

A technique to shape a transmit field by dynamic controlled coupling in MRI applications is disclosed. The technique described herein proposes dynamic adjustment of the complex loop impedance of a secondary coil in order to modify the coupling with a primary transmit field. A controllable secondary field is created thereafter, shaping the overall transmit field.
