Non-invasive method for the assessment of non-linear elastic properties and stress of forearm arteries in vivo

Nikolaos Stergiopoulos, Jean-Jacques Meister

AIM: To propose a method for obtaining non-invasive highly accurate measurements of arterial diameter, thickness and pressure at a single location on a peripheral arm artery, and use this data to estimate the status of the arterial wall. METHODS: Diameter ...

Numerical study of pressure and flow propagation in arteries

Nikolaos Stergiopoulos

A computer model for simulating pressure and flow propagation in the human arterial system is developed. The model is based on the one-dimensional flow equations and includes non-linearities arising from geometry and material properties. Fifty five arteria ...

Non-invasive estimate of the mechanical properties of peripheral arteries from ultrasonic and photoplethysmographic measurements

Jean-Jacques Meister

The non-linear elastic response of arteries implies that their mechanical properties depend strongly on blood pressure. Thus, dynamic measurements of both the diameter and pressure curves over the whole cardiac cycle are necessary to characterise properly ...

The inverse Womersley problem for pulsatile flow in straight rigid tubes

Nikolaos Stergiopoulos

In this study a numerical solution for the problem of pulsating flow in rigid tubes is described. The method applies to the case of known flow rate waveform, as opposed to Womersley solution where the pressure gradient was the known quantity. The solution ...
