Comparison of ultrasound vector flow imaging and CFD simulations with PIV measurements of flow in a left ventricular outflow trackt phantom - Implications for clinical use and in silico studies
Leinan, Paul Roger; Grønli, Thomas; Skjetne, Paal; Wigen, Morten Smedsrud; Urheim, Stig; Løvstakken, Lasse; Dahl, Sigrid Kaarstad (Peer reviewed; Journal article, 2022)In this study we have compared two modalities for flow quantification from measurement data; ultrasound (US) and shadow particle image velocimetry (PIV), and a flow simulation model using computational fluid dynamics (CFD). ... -
Influence of the Dynamic Motion of the Atrial Wall on the Hemodynamics in the Human Left Atrium: A Computational Fluid Dynamics Study
Skjefstad, Vegard Slettahjell (Master thesis, 2020)Hjerte- og karsykdommer er den ledende dødsårsaken i Europa, der atrieflimmer (AF) er en av de viktigste årsakene, og utbredelsen forventes å øke de kommende årene. Etterspørselen etter bedre diagnostikk og behandling av ... -

Patient Specific Numerical Simulation of Flow in the Human Upper Airways for Assessing the Effect of Nasal Surgery
Jordal, Maria Rolstad; Johnsen, Sverre Gullikstad; Dahl, Sigrid Kaarstad; Müller, Bernhard (Lecture, 2017)The study is looking into the potential of using computational fluid dynamics (CFD) as a tool for predicting the outcome of surgery for alleviation of obstructive sleep apnea syndrome (OSAS). From pre- and post-operative ... -

Prediction of guidewire-induced aortic deformations during EVAR: a finite element and in vitro study
Emendi, Monica; Støverud, Karen-Helene; Tangen, Geir Arne; Ulsaker, Håvard; Manstad-Hulaas, Frode; Di Giovanni, Pierluigi; Dahl, Sigrid Kaarstad; Langø, Thomas; Prot, Victorien Emile (Peer reviewed; Journal article, 2023)Introduction and aims: During an Endovascular Aneurysm Repair (EVAR) procedure a stiff guidewire is inserted from the iliac arteries. This induces significant deformations on the vasculature, thus, affecting the pre-operative ... -
Velocity profiles in a 2D model of the left ventricular outflow tract, pathological case study using PIV and CFD modeling
Leinan, Paul Roger; Skjetne, Paal; Morud, John; Urheim, Stig; Dahl, Sigrid Kaarstad (Chapter, 2017)In the current study, we present an experimental (in vitro) 2D flow model for studying blood flow in the human left ventricular outflow tract (LVOT) and the first part of the aorta using particle image velocimetry (PIV) ...
