Abstract
Morphology of cardiovascular tissue is influenced by the unsteady
behavior of the blood flow and vice versa. Therefore, the pathogenesis of several
cardiovascular diseases is directly affected by the blood-flow dynamics. Understand-
ing flow behavior is of vital importance to understand the cardiovascular system and
potentially harbors a considerable value for both diagnosis and risk assessment. The
analysis of hemodynamic characteristics involves qualitative and quantitative inspec-
tion of the blood-flow field. Visualization plays an important role in the qualitative
exploration, as well as the definition of relevant quantitative measures and its vali-
dation. There are two main approaches to obtain information about the blood flow:
simulation by computational fluid dynamics, and in-vivo measurements. Although
research on blood flow simulation has been performed for decades, many open prob-
lems remain concerning accuracy and patient-specific solutions. Possibilities for real
measurement of blood flow have recently increased considerably by new develop-
ments inmagnetic resonance imagingwhich enable the acquisition of 3Dquantitative
