Image phase has unique information about tissue composition such as gray and white matter structures. Phase imaging is used for various imaging methods such as susceptibility weighted imaging and quantitative susceptibility mapping. To obtain phase image, long echo time is needed to acquire sufficient phase shift. However, there is limitation due to the B0 inhomogeneity artifacts (i.e. signal loss in the frontal and sinus regions). One method to solve this problem in 3D imaging is the 3D z-shimming method.
