| Abstract(in English) | Based on the phased tracking method, it is newly found that there are high frequency components from d.c. to several hundred Hz in the vibrations on the arterial wall noninvasively measured in in vivo experiments. These vibrations are mainly caused by the blood flow, and the wall vibration propagates from the intima to the adventitia. Moreover, the propagation characteristics of the vibration will highly depend on the viscoelasticity in the arterial wall. In this report, the shear viscoelasticity is estimated from the propagation characteristics of the shear wave in the regional area of the arterial wall in the frequency domain. The proposed method was applied to human common carotid arteries. |
