Time Domain Reflectometry in a Model of the Arterial System

  • P. Sipkema

The arterial tree can be characterized by means of its frequency response function (the input impedance) and by means of its time response function (the impulse response function). These descriptions are Fourier transforms of each other. If the impulse excitation is supplied by a special generator that has an impedance matched to that of the characteristic impedance of the ascending aorta, then the analysis is called time domain reflectometry.
