Traveling wave MRI antenna device for use during treatment of patient, has planar radio frequency line synthesized by targeted artificial influencing of characteristic properties of wave numbers

摘要

The device has a planar radio frequency line synthesized by targeted artificial influencing of characteristic properties of wave numbers. Pulsed high-frequency magnetic fields are generated at two ends of an open investigation volume (13) of a traveling wave MRI part (10). The MRI part adds static main magnetic field. A temporary displacement of nuclear spins is initiated. The pulsed alternating fields are directly received for determination of local field strength.
