Abstract
This paper presents flow results of a magnetic resonance imaging velocimetry system which relies on fluid motion estimation, and uses vorticity map differencing for calibrating its reliability. To validate this new concept, phase contrast magnetic resonance imaging on the right atrium of a healthy subject has been suggested. The study has demonstrated the state of change in blood flow patterns within a cardiac chamber using our implemented system and a well established flow imaging modality. Based on the gold standard imaging technique, flow fields can be used to establish a set of reference data to compare against magnetic resonance fluid motion tracking results. We conclude that our validated technique can be reliable enough for establishing a cardiac based velocimetry system.
