Abstract
A system and method of mapping and correcting the inhomogeneity of a magnetic field within an object using an Magnetic Resonance Imaging (MRI) system where there is a single dominant resonance. The method includes acquiring at least three MRI images, each at different echo times (TE). At least two ΔTE images (ΔTE) are generated based on the at least three MRI images, wherein the subscripts I=1 N refer to images with sequentially increasing ΔTE times. Aliasing in the ΔTEimage is permitted. The ΔTE times of ΔTEand ΔTEare set such that the alias points at which wrapping occurs in ΔTEdoes not overlap with the alias points of ΔTE. Each ΔTE image is unwrapped. A final B0 map is set to the unwrapped ΔTEimage.
