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.

本研究的目的是开发一种高精度的血管性质估计系统。为了实现这一目的，一种能够以期望的模式改变血管压力的系统被开发出来。此外，还提出了一种检测脉冲波到达传感器时间的新算法。利用该系统进行的实验表明，通过根据身体另一侧测量的血压来控制血管中的压力，有可能减少血管特性估计中的个体差异。该算法对脉冲波中的噪声具有较强的鲁棒性。
