Abstract
Reduces artifacts in fast imaging sequences used in magnetic resonance imaging by changing the phase of the radio frequency pulse output of a synthesizer in order to prevent the transverse magnetization caused by the radio frequency pulses used for "tipping" aligned spins into the transverse plane from reaching a steady state condition. Steady state conditions are known to cause artifacts in the final images.
