## Abstract Signal phase variations caused by physiology are a major source of instability in fMRI images produced by multiple RF pulses. __k__βSpace phase variation maps show cyclic phase variations at the frequency of respiration combined with a cardiac variation of lower amplitude. The amplitude
## Abstract A new approach to understanding and reducing motion artifacts in magnetic resonance imaging (MRI) is introduced. This paper presents a novel technique for correcting generalized motion artifacts arising from translation, rotation, dilation, and compression, or any combination thereof. W
