Virtually every phase-contrast MRI (PC-MRI) measurement is contaminated with background phase (BP) from eddy currents and concomitant gradient terms. A widely reported method to correct BP relies on a polynomial fitting of the static pixels within regions of static tissue. This method requires sufficient static tissue in close proximity to the region of interest—a requirement that cannot be met for imaging of the heart or great vessels. In this work, we propose a BP correction method that leverages information from multiple slices collected under identical conditions but with different table positions.
