Phase contrast measurements can either be acquired with a breath-held segmented acquisition or a free-breathing acquisition with multiple averages to mitigate respiratory motion artifacts. The breath-held techniques require long breath-holds that are poorly tolerated by patients and the multiple average acquisitions are time consuming and suffer from reduced vessel edge sharpness. This work proposes a new approach for free breathing phase contrast velocity measurements where motion correction is explicitly integrated into the reconstruction along with non-linear parallel imaging. The technique provides faster high-resolution free breathing flow quantification.
