论文摘要
目前的贡献涉及通过利用超声多普勒测量值来估计血液动力学量的估计。基于PBDW方法提出了一种快速方法。描述了几种方法上的贡献：引入了一个子序列分区以改善降级近似，比较了两种不同的估计压降的方法，并得出了误差估计。提出了关于现实的颈动脉几何形状的测试案例，这表明鉴于现实的应用，所提出的方法是有希望的。
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 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 test-case on a realistic common carotid geometry is presented, showing that the proposed approach is promising in view of realistic applications.
