In this work, we evaluate Jenkinson's PRELUDE phase unwrapping method on phase contrast magnetic resonance imaging flow data of the human aorta. For the evaluation, we used aquired data from a volunteer as well as a simple digital phantom. We set up an image processing pipeline employing PRELUDE, and finally evaluate the performance of the method qualitatively and quantitatively using the misclassification rate and execution speed as metrics.
