Reduction strategies for shape dependent inverse problems in haemodynamics

Gianluigi Rozza, Andrea Manzoni, Toni Mikael Lassila

This work deals with the development and application of reduction strategies for real-time and many query problems arising in fluid dynamics, such as shape optimization, shape registration (reconstruction), and shape parametrization. The proposed strategy ...

The activation of the cannabinoid receptor type 2 reduces neutrophilic protease-mediated vulnerability in atherosclerotic plaques

Nikolaos Stergiopoulos, Katia Galan, Rafaela Fernandes Da Silva, Luciano Dos Santos Aggum Capettini

The activation of cannabinoid receptor type 2 (CB2)-mediated pathways might represent a promising anti-atherosclerotic treatment. Here, we investigated the expression of the endocannabinoid system in human carotid plaques and the impact of CB2 pharmacologi ...

An Efficient Segmentation Method for Ultrasound Images based on a Semi-supervised Approach and Patch-based Features

Jean-Philippe Thiran, Meritxell Bach Cuadra, Xavier Bresson, Nawal Houhou, Anca-Ramona Ciurte, Alessia Pica

Segmenting ultrasound images is a challenging problem where standard unsupervised segmentation methods such as the well-known Chan-Vese method fail. We propose in this paper an efficient segmentation method for this class of images. Our proposed algorithm ...

Design and Psychophysical Evaluation of a Tactile Pulse Display for Teleoperated Artery Palpation

Hannes Bleuler, Roger Gassert, Philippe Rétornaz, Laura Santos Carreras, Kaspar Leuenberger

During traditional open procedures, surgeons directly palpate tissues before dissecting them. In this way, they can avoid the accidental damage of hidden arteries that can lead to fatal hemorrhage. New Minimally Invasive Surgical (MIS) techniques progressi ...

A Real-Time Simulator for Interventional Radiology

Hannes Bleuler, Lindo Robert Duratti, Fei Wang, Evren Samur

Interventional radiologists manipulate guidewires and catheters and steer stents through the patient’s vascular system under X-ray imaging for treatment of vascular diseases. The complexity of these procedures makes trainingmandatory in order to master han ...

Effect of elastin degradation on carotid wall mechanics as assessed by a constituent-based biomechanical model

Nikolaos Stergiopoulos, Sylvain Roy, Luca Augsburger, Edouard Fonck, Gilles Prod'Hom

Arteries display a nonlinear anisotropic behavior dictated by the elastic properties and structural arrangement of its main constituents, elastin, collagen, and vascular smooth muscle. Elastin provides for structural integrity and for the compliance of the ...

144Ce as a potential candidate for interstitial and intravascular brachytherapy

Rakesh Chawla, François Bochud

To investigate the suitability of 144Ce for both interstitial and intravascular brachytherapy applications. Monte Carlo calculations of radial dose rate distributions in water were performed for 144Ce in a spring-shaped source and compared with two commonl ...

Conductance catheter-based assessment of arterial input impedance, arterial function, and ventricular-vascular interaction in mice

Nikolaos Stergiopoulos, Patrick Segers, Nico Westerhof

Global assessment of both cardiac and arterial function is important for a meaningful interpretation of pathophysiological changes in animal models of cardiovascular disease. We simultaneously acquired left ventricular (LV) and aortic pressure and LV volum ...
