1. A system for measurement of pulse wave velocity of a vessel, comprising:
an intravascular device configured to provide plurality of measurements along the length of the vessel, wherein the intravascular device comprises two markers provided at different locations along the length of the intravascular device of which positions are localizable by a tracking apparatus;
an apparatus configured to:
receive the plurality of measurements from the intravascular device;
receive position information of the two markers from the tracking apparatus;
associate for a first time a measurement of the plurality of measurements with the positions of the markers, wherein the first marker is in a first position and the second marker is in a second position;
detect upon movement of the intravascular device from the position information when the first marker reaches the second position and associate a second time;
ascertain the pulse wave velocity value of the vessel based on measurements associated for the first time and the second time from the plurality of measurements and based on the distance between the locations of the two markers along the length of the intravascular device.
