We present a modified method for quantifying the magnetic susceptibility for arbitrary shaped objects from high-resolution susceptibility weighted phase images. The inverse problem of going from the relative difference field (RDF) to the magnetic susceptibility was extended by a shutter and a possible offset of the RDF. The field inhomogeneity pattern seen in phase images was efficiently removed in the susceptibility maps.
