Background, Motivation and Objective Vector flow mapping (VFM) is a promising tool for capturing 2D flow vectors in the left ventricle (LV) and opening up new prospectives. By using color flow mapping (CFM) and a fluid physical law, VFM estimates azimuth velocities under assumed 2D planar flow. Besides typical CFM artifacts, a major factor causing VFM uncertainty is flow through the image plane. Since through-plane flows (TPFs) differ according to each measurement, VFM accuracy also depends on each measurement, implying that VFM-based diagnosis might be unreliable. Given that the accuracy of each VFM measurement is known, the quality of VFM-based diagnosis can be improved by rejecting or retaking unreliable VFM results.
