Abstract :
We identify the pulsation dynamics of blood flow comparing them with previously extracted periodic orbits. We show an algorithm for the extraction of periodic orbits from observed dynamics. The identification of the dynamics was performed by calculating the distance between the trajectory of the target dynamics and the extracted periodic orbits. We evaluated its performance by the time ratio so that the target dynamics are closest to each periodic orbit
