Abdominal aorta ultrasound scan. (a) B-mode image sequence was used to derived diameter and distension. (b) PW-Doppler signal was used to plot diameter-flow velocity loop thus evaluating PWV_abd. Aortic pulse pressure was derived from PWV_abd and distension measurements. Furthermore, blood flow velocity signal was used to derive wall shear rate measurements. Carotid artery ultrasound scan. (c) B-mode image sequence was used to derived diameter and distension. (d) PW-Doppler signal was used to plot diameter-flow velocity loop thus evaluating PWV_car. Furthermore, blood flow velocity signal was used to derive wall shear rate measurements.
