Claim Text:
1. A method of operation in at least one component of a medical imaging system that employs volumetric phase-contrast magnetic resonance imaging (MRI) data, the method comprising: receiving volumetric phase-contrast MRI data that includes a plurality of voxels; identifying at least one set of voxels that represent static soft tissue; generating via at least one computer at least one eddy current related phase offset based on the at least one set of voxels that represent static soft tissue; and performing a phase error correction based at least in part on the generated at least one eddy current related phase offset, wherein identifying at least one set of voxels that represent static soft tissue includes: applying a first filter to the volumetric phase-contrast MRI data, the first filter based on an intensity value of a magnitude associated with the voxels of the volumetric phase-contrast MRI data; applying a second filter to the volumetric phase-contrast MRI data, application of the second filter which excludes air and lung tissue from the volumetric phase-contrast MRI data; and applying a third filter to the volumetric phase-contrast MRI data, application of the third filter which excludes blood and other moving tissue from the volumetric phase-contrast MRI data.
