Abstract: PROBLEM TO BE SOLVED: To provide a system and a method for determining an arterial pulse transit time of a subject of interest in a remote sensing environment.SOLUTION: A video imaging system is used to record time-varying source images of a proximal region and a distal region of a subject intended to be analyzed for arterial pulse transit time. A time series signal for each of the proximal and distal regions is extracted from the source images, and a phase of each of the extracted time series signals is computed. A difference is then computed between these phases. This phase difference is a monotonic function of frequencies in the signals. An arterial pulse transit time of the subject is extracted from the monotonic function. The arterial pulse transit time of the subject is then transmitted to a computer system. The computer system determines blood pressure, blood vessel blockage, blood flow velocity, or a peripheral neuropathy.
