Cardiovascular disease is one of the most important health problems worldwide and its prevalence is expected to rise [1]. A screening method to detect risk for cardiovascular events is much sought after. A major factor in cardiovascular problems is increased arterial stiffness, or arteriosclerosis [2]. Every heartbeat, a pulse wave emerges from the heart, propagating through the arteries at a velocity in the range of 5-13m/s in a healthy person: the pulse wave velocity (PWV). PWV is proportional to arterial stiffness, and PWV has a strong predictive value for cardiovascular disease and overall mortality. A possible approach to detect arteriosclerosis is to measure PWV locally, at the common carotid artery (CCA) in the neck. The CCA is easily accessible, and it has great physiological importance in onset and progress of cardiovascular health problems [3]. In the proposed work, PWV is assessed in the CCA using fringe pattern topography (FPT).
