Patent ID: 8283925

Claim:
A method for generating a diffusion-weighted magnetic resonance image that is substantially free of image distortions, comprising the steps of: obtaining a first adjustment magnetic resonance dataset of an examination subject in a magnetic resonance data acquisition unit by implementing a magnetic resonance data acquisition sequence with a first diffusion weighting in said magnetic resonance data acquisition unit; obtaining a second adjustment magnetic resonance dataset of the examination subject in the magnetic resonance data acquisition unit by implementing a magnetic resonance data acquisition sequence with a second diffusion weighting in said magnetic resonance data acquisition unit; obtaining one of said first or second adjustment magnetic resonance datasets with a predetermined diffusion weighting in three orthogonal diffusion directions; and providing said first and second adjustment magnetic resonance datasets to a processor and, in said processor, automatically calculating correction parameters, in each of said three orthogonal diffusion directions that de-skew diffusion weighted magnetic resonance images, and making said correction parameters available at an output of said processor in a form allowing correction of a subsequently-obtained diffusion-weighted diagnostic magnetic resonance image with said correction parameters to substantially correct for image distortions arising due to the diffusion-weighting in said diagnostic magnetic resonance image.
