The authors have used ultrasound to estimate noninvasively mechanical properties such as circumferential elastic modulus, E sigma , of the aorta. The value of E sigma , as well as other mechanical properties depends on the wall thickness. Wall thickness data based on ultrasound imaging are compared with those obtained from direct measurements of fixed aortic preparations. Initial results suggest the wall thickness measured using ultrasound is an overestimation of the actual thickness. However, the ultrasound value appears to correlate with that measured from histological sections made on aortas fixed in situ.
