Beschreibung
Zusammenfassung:	The invention provides a system and a method for calculating a pulse wave velocity based on a plurality of intravascular ultrasonic pulses directed along a vessel. For each ultrasonic pulse, a plurality of echoes is received from a plurality of distances along the vessel. A first ultrasound Doppler signal is received from a first distance from the pulse origin and a second ultrasound Doppler signal from a second distance from the pulse origin. A first and second flow velocity metric is obtained based on the first and second ultrasound Doppler signal, respectively. The pulse wave velocity is calculated based on the time delay, which is based on the first flow velocity metric and the second flow velocity metric.
