Vascular impedance is a frequency dependent quantity relating a vascular compartment's flow dynamics to pressure changes. Although vascular impedance has been investigated in larger arteries using Doppler ultrasound, probing the smaller microvasculature using similar techniques is difficult due to their small cross-sectional area. However, recent developments using diffuse optics have enabled the possibility of measuring blood flow and volume in arterioles and other microvasculature. This research presents a method to estimate the arteriole impedance non-invasively using diffuse correlation spectroscopy (DCS) as well as near-infrared spectroscopy (NIRS).
