Research Abstract

The purpose of this study is development of estimating system for a vascular property with high accuracy. To fulfill this purpose, a system that can change pressure in the blood vessel in desired patterns was developed. In addition, a new algorithm to detect arrival times of pulse waves at a sensor was also developed. An experiment using the developed system showed that there is a possibility to decrease intraindividual variability in the vascular property estimation by controlling pressure in the blood vessel according to blood pressure measured in the other side of the body. And the proposed algorithm was relatively robust to noise included in pulse waves.
