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).
