Medical interventions in the central nervous system (CNS) are challenging due to the complexity and delicacy of the brain tissue. Techniques that do not require opening the skull would alleviate patient discomfort and increase post-operative outputs. Vesse ...
EPFL2022Model order reduction of flow based on a modular geometrical approximation of blood vessels
Simone Deparis, Luca Pegolotti
We are interested in a reduced order method for the efficient simulation of blood flow in arteries. The blood dynamics is modeled by means of the incompressible Navier–Stokes equations. Our algorithm is based on an approximated domain-decomposition of the ...
2021Remote Blood Pulse Analysis for Face Presentation Attack Detection
Sébastien Marcel, Guillaume Heusch
In this chapter, the usage of Remote Photoplethysmography (rPPG\index{Remote Photoplethysmography (rPPG)}) as a mean for
face presentation attack detection is investigated. Remote
photoplethysmography consists in retrieving the heart-rate of a subject from ...
Springer20193D phase contrast MRI: Partial volume correction for robust blood flow quantification in small intracranial vessels
Mohamed Farhat, Pierre Bouillot
Purpose: Recent advances in 3D-PCMRI (phase contrast MRI) sequences allow for measuring the complex hemodynamics in cerebral arteries. However, the small size of these vessels vs spatial resolution can lead to non-negligible partial volume artifacts, which ...
2018Hierarchical Cardiac-Rhythm Classification Based on Electrocardiogram Morphology
David Atienza Alonso, Amir Aminifar, Elisabetta De Giovanni, Dionisije Sopic
Atrial Fibrillation (AF) is a type of cardiac arrhythmia that significantly increases the risk of stroke and heart failure. In general, in the case of patients affected by AF, their electrocardiogram (ECG) shows a typical pattern of irregular RR intervals ...
2017Oxygen defects in GaAs: A hybrid functional study
Alfredo Pasquarello, Davide Colleoni
Using hybrid density functional calculations, we address the structural properties, formation energies, and charge transition levels of a variety of oxygen defects in GaAs. The set of considered defects comprises the bridging O atom in a As-O-Ga configurat ...
Amer Physical Soc2016Extracting Atrial Activations from Intracardiac Signals during Atrial Fibrillation using Adaptive Mathematical Morphology
Jean-Marc Vesin, Sasan Yazdani, Andréa Buttu, Etienne Pruvot
The detection of intracardiac activities is a major issue in the processing of atrial fibrillation signals. we evaluate a method based on mathematical morphology with an adaptive structuring element in order to extract the atrial activations from intracard ...
2015High pre-ablation ECG organization in long-standing persistent atrial fibrillation terminated within the left atrium
Jean-Marc Vesin, Andréa Buttu, Jérôme Sébastien Van Zaen, Etienne Pruvot
The outcome of stepwise catheter ablation (step-CA) for patients (pts) with long-standing atrial fibrillation (LS-pAF) is poorly predicted by classical organization indices (OI). Our study aims at developing new indices from pre-ablation ECG in order to id ...
2013Isogeometric Analysis of PDEs and numerical implementation in the Finite Element Library LifeV
The aim of the project is double: to understand the flexibility of the Isogeometric Analysis tools through the solution of some PDEs problems; to test the improvement in the computational time given by a partial loops vectorization at compile-time of the L ...
2012Pressure and Flow Wave Propagation in Patient-Specific Models of the Arterial Tree
Blood flow in the arterial circulation induces hemodynamic forces that play an important role in various forms of vascular diseases. Temporal variation of the wall shear stress seems to play a significant role in atherogenesis and plaque stability. Flow in ...
