Patent ID: 8498461

Claim:
A method to determine magnetic resonance (MR) system-dependent phase information of a phase value in an MR phase image data set, comprising the steps of: providing a first MR phase image data set to a processor that was acquired by operation of an MR system, said first MR phase image data set representing a plurality of image points; in said processor, associating initial variances with respective image points of said first phase image data set; for calculating an additional phase image data set, estimating, in said processor, a phase value and a phase variance of the phase value for respective image points of said second phase image data set by a linear transformation of said image points of said first phase image data set; and in said processor, calculating said second phase image data set by a weighted addition of the phase values of the first phase image data set with the estimated phase values, said weighting being dependent on the estimated variance of the phase value.
