Abstract
View-to-view phase shifts due to B0 instability are corrected by applying a phase correction to the low-spatial-frequency views. The algorithm described herein assumes that the signal intensity in the space outside of an object represents only noise. A set of phases for the low-spatial-frequency views are calculated by minimizing, in the image, the intensity of the induced artifacts in the space outside of the object.
