Biological artery models, cultured in a bioreactor-platform with adjustable pulsatile flow conditions, represent a potential in vitro test system for atherosclerosis research and provide a suitable tool for the development of new flow quantification techniques as well as studies of arterial elasticity and flow dynamics ex vivo and in vitro. A major requirement for these studies is viable motion synchronization in order to achieve time-resolved flow measurements. We present a new platform that uses self-navigation instead of external trigger signals for measurements of 2D- and 4D flow dynamics, vessel wall morphology and quantifications of arterial pulse-wave-velocity and wall shear stress.
