Abstract

The invention discloses a method, and devices for determining volume flow, blood velocity profile, artery wall properties of a tubular conduit system, stenosis identification and localization by introducing an artificial pressure (5) or flow excitation signal (a single signal or multiple signals) into the blood vessel (2) (or in any other tubular flowing fluid conduits), and or using natural heart beat signals measurement and analysis of the vessel wall displacements or vessel diameter changes.
