In this work, a new method is proposed for automatic extraction of the left ventricular diastolic transmitral vortex ring from 3D whole-heart three directional Phase Contrast MRI.  ...  In the training step, an average reference signature of the complex transmitral vortex ring is captured from training subjects using Laplace-Beltrami spectrum and the Lambda2 method.  ...  signature based extraction is rather accurate in extracting LV diastolic transmitral vortex rings from whole heart PC-MRI with 27 successfully extracted LV vortex rings out of the total 32 rings yielding  ...
