A New Noninvasive Approach to Detect the Artery´s Pulsating Properties via Tissue Control Method

This paper presents a new approach, named as tissue control method, to obtain the pulsating properties for artery. These properties are the variations of blood vessel diameter, instantaneous intra-arterial blood pressure, and the dynamic impedances of blood vessel. By maintaining the stiffness of tissue and tracking the variations of blood pressure at a critical location, it decouples the effect of the arterial pulsation from the tissue and measures the variations of the blood vessel diameter. Then employ the identification technique to obtain the mechanical impedances of the arterial blood vessel, and subsequently estimate the instantaneous blood pressure in the artery. The results of animal experiments show that the tissue control method is feasible to detect the pulsating properties of the artery.
