The present contribution deals with the estimation of haemodynamics Quantities of Interest by exploiting Ultrasound Doppler measurements. A fast method is proposed, based on the Parameterized Background Data‐Weak (PBDW) method. Several methodological contributions are described: a sub‐manifold partitioning is introduced to improve the reduced‐order approximation, two different ways to estimate the pressure drop are compared, and an error estimation is derived. A fully synthetic test‐case on a realistic common carotid geometry is presented, showing that the proposed approach is promising in view of realistic applications.
