Structured mesh generation from doppler ultrasound images
Non-invasive ultrasound imaging of human arteries is a widely form used for medical diagnosis of arterial diseases, like atherosclerosis. The objective of this paper is to present a methodology for patient-specific construction of a structured mesh of the carotid artery bifurcation from images obtained with Doppler ultrasound techniques.
Mesh generation and blood flow simulation in human carotid bifurcation
The ability to associate blood flow features with parameters representative of the vessel geometry is fundamental to perform studies that might help surgeons understand the development of artery diseases. A tool to generate structured computational meshes for vascular modeling frameworks and a three dimensional finite element model for blood flow simulation is presented here. Blood flow is described by the incompressible Navier-Stokes equations and the simulation is carried out under pulsatil...
FLUID-STRUCTURE INTERACTION MODELING OF BLOOD FLOW IN A NON-STENOSED COMMON CAROTID ARTERY BIFURCATION
The rupture of atherosclerotic plaques is known to be associated with stresses that act on or within the arterial wall and is one of the leading causes of mortality and disability worldwide. In this study a fluid-structure interaction modeling of blood flow in a non-stenosed common carotid artery bifurcation is carried out using vascular geometries reconstructed from Doppler ultrasound images. Comparison of results between rigid wall model and fluid-structure interaction model is presented.
Hemodynamics of a stenosed carotid bifurcation
A methodology for computational 3D reconstruction and structured hexahedral meshing for patient-specific hemodynamics analysis of the carotid artery bifurcation with a stenosis is presented. The purpose of this work is the use of anatomically realistic blood flow simulations by the finite element method (FEM) derived from in vivo medical imaging to make patient specific studies of flow phenomena associated with the development of atherosclerosis disease. Blood flow is described by the incompr...
New Challenges in the Higher education area: university networks for internationalization and globalization.
The "A NAME for Health" project, funded by the EDULINK program, is a project that establishes A Network Approach in Medical Education (NAME) for the Pursuit of Quality in Higher Education Institutions (HEIs) and Health Systems. It aims to improve Health Care through an ongoing intervention quality program on Medical Education, at 4 HEIs in Portugal, Angola and Mozambique: Faculty of Medicine of University of Porto (project coordinator), Portugal; Faculty of Medicine of Agostinho Neto Universi...
