Abstract

In this paper we investigate the dynamics of contrast agent concentration as blood flow estimation method utilizing contributions from three different fields: morphologic and dynamic angiographic X-ray scans, computational fluid dynamics (CFD) simulations and Laser-Doppler-Velocimetry (LDV) measurements. Based on dynamic angiographic X-ray measurements we exploit dedicated CFD simulations, carried out specifically for each target object, for the adaptation of the plain video densitometric results. Finally, a comparison with LDV is presented.
