Abstract:
1. A system for Magnetic Resonance (MR) imaging of a body placed in an examination volume, the system comprising: a first coil configured to establish a substantially homogeneous main magnetic field in the examination volume; a second coil configured to generate switched magnetic field gradients superimposed upon the main magnetic field; a third coil configured to radiate circularly polarized RF signals towards the body; a controller coupled to the first, second and third coils and configured to control the generation of the magnetic field gradients and a direction of circular polarization of the RF signals generated by the third coil to be selectable between forward polarization and reverse polarization; a receiver configured to receive and sample MR signals; a processor configured to form MR images from the MR signal samples; and an object having an RF antenna configured to receive RF signals generated by the third coil.
