1. A method for acquiring magnetic resonance (MR) image data, comprising:
operating an MR data acquisition device to acquire at least two temporally separate raw data sets, each representing a plurality of pixels, with one phase measurement value being acquired for each pixel in each raw image data set; providing said raw image data sets to a processor and, in said processor, executing an optimization algorithm for shared calculation of corrected phase values for the pixels in the respective raw image data sets, with corrected phase values for the pixels in a first of the raw image data sets being, for each pixel, dependent at least one the phase measurement value of the respective pixel at a same location in a second of the raw image data sets acquired before or after said first of said raw image data sets, and wherein corrected phase values of the respective pixels in the second of the raw image data sets, for each pixel, being dependent at least one the phase measurement value of the pixel at the same location in said first of said raw image data sets; and in said processor, generating corrected image data sets from the corrected phase values, and making the corrected image data sets available in electronic form at an output of said processor. |
