We quantitavely compare different methods for removing background field inhomogenities in susceptibility weighted phase imaging. We discovered that the commonly used homodyne-filter changes phase differences while other methods e.g. spherical mean value estimation keep phase differences and properly reduce background field inhomogenities.
