Changes in the biomechanical functions of artery serve as important indicators for prediction of cardiovascular disease. Endothelial dysfunction is known to play a role to develop atherosclerosis and cardiovascular disease. Ultrasound measurement of flow-mediated dilation of the brachial artery is a method to quantify endothelial function based on changes in arterial diameter. One challenge of the ultrasonic arterial measurement is the compression of the artery due to the weight of a conventional ultrasound probe employed, resulting in the error on the diameter estimation. One approach to address this issue with low-cost is to use a wearable ultrasound sensor which is flexible and lightweight so that it does not deform the artery of interest beneath the sensor during the measurement. In this paper, the capability of the wearable sensor to measure the change in arterial diameter is investigated.
