Abstract:
A magnetic resonance apparatus comprising:a magnet assembly which generates a temporally constant main magnetic field through an examination region; a first RF coil assembly disposed on a first side of the examination region; a second RF coil assembly disposed on a side of the examination region; at least one RF transmitter that transmits individual radio frequency resonance excitement and manipulation pulses to the first and second RF coil assemblies to induce and manipulate resonance; an RF tip angle calculator which receives and measures the resonance induced by the first RF coil assembly separately from the resonance induced by the second RF coil assembly within a selected region of the subject; and, a means for independently adjusting the individual radio frequency pulses transmitted to the first and second coil assemblies to adjust the tip angles of the induced resonance to produce a selected combined tip angle in the selected region.
