Some methods for evaluating the degree of arteriosclerosis utilizing the magnitude of systaltic movement of carotid artery have been proposed. The magnitude of carotid movement depends on the stiffness of surrounding tissues around carotid artery as well as the stiffness of carotid artery itself. Therefore, accurate criterion for the degree of arteriosclerosis cannot be obtained only by observing the magnitude of carotid movement. This study proposes an estimation method of the "self-"stiffness of carotid artery by excluding influence of the stiffness of surrounding tissues. In the proposed method, the systaltic movement of surrounding tissues as well as carotid artery is tracked by an optical flow method using ultrasonic B-mode images drawing the cross section of carotid artery.
