Abstract

It is important for early diagnosis of arteriosclerosis to noninvasively measure the local elasticity of the arterial. To improve the spatial resolution in the local velocity measurement of vibration propagating on the arterial wall, this paper proposes a new method to actuate impulsive wave with higher frequency components until 1 kHz from the backbone and transcutaneously measure the transit delay time of the impulsive wave propagating two proximate points on the aortic wall. The method offers potential for research in acoustical diagnosis of arteriosclerosis.
