It has been shown that vortex blood flow patterns are physiologically present in the heart, aorta, and pulmonary circulation, but can also be correlated to certain pathologies. The purpose of this work was to define new objective and quantitative measures for three-dimensional vortex flow evaluation. These measures were then used for the exemplary characterization of helical blood flow found in the healthy aortic arch (evaluated in 9 healthy subjects), as well as altered flow patterns in pathologically dilated aortas (3 patients).
