Abstract(in English) | We simultaneously detect small vibrations at the two points on the Aortic Wall near a heart using two Ultrasonic transducers.By applying the spectrum analysis to the resultant two vibration signals,the transfer function between the two vibrations is obtained.The gradient of the phase characteristic of the transfer function gives a transmit delay time of pulse wave due to propagation between two points.From the resultant transmit delay time and distance between two points,regional Pulse Wave Velocity(PWV)is obtained.At the same time,the reliability of these analysis is checked by using the coherence function.From the experimental results,propagation characteristics of the velocity of the pulse wave on the blood vessel is obtained.These regional acoustic properties of the blood vessel will be very useful for diagnosis of the Arteriosclerosis. |
