ABSTRACT:
A system and method for MR magnetic field mapping includes a computer programmed to acquire a first data point at a first location in a first phase image data set, a second data point at the first location in a second phase image data set, a third data point at the first location in a third phase image data set. The first, second, and third phase images are acquired using a first, second, and third TE, respectively. Phase wrapping does not occur among the first and second phase image data sets; however, phase wrapping does occur among the second and third phase image data sets. The computer is also programmed to determine a magnetic field inhomogeneity, wherein the determination of the magnetic field inhomogeneity is based on the first, second, and third data points.
