A coupled hydrodynamic model of the cardiovascular and cerebrospinal fluid system

Nikolaos Stergiopoulos, Philippe Reymond, Bryn Andrew Martin

Martin BA, Reymond P, Novy J, Baledent O, Stergiopulos N. A coupled hydrodynamic model of the cardiovascular and cerebrospinal fluid system. Am J Physiol Heart Circ Physiol 302: H1492-H1509, 2012. First published January 20, 2012; doi: 10.1152/ajpheart.006 ...

The segmentation of MR images of the neonatal brain is an essential step in the study and evaluation of infant brain development. State-of-the-art methods for adult brain MRI segmentation are not applicable to the neonatal brain, due to large differences i ...

We propose a new approach for the data assimilation and simulation of anatomically correct left ventricle fluid dynamics based on cardiac magnetic resonance images. The movement of the ventricle is captured by a set of tracking points on the endocardium id ...

Wiley InterScience2012

Cerebrospinal fluid (CSF) dynamics in the cervical spinal subarachnoid space (SSS) have been thought to be important to help diagnose and assess craniospinal disorders such as Chiari I malformation (CM). In this study we obtained time-resolved three direct ...

Ventricle Equilibrium Position in Healthy and Normal Pressure Hydrocephalus Brains Using an Analytical Model

Jean-Marie Drezet, Bryn Andrew Martin, Kamal Shahim

The driving force that causes enlargement of the ventricles remains unclear in case of normal pressure hydrocephalus (NPH). Both healthy and NPH brain conditions are characterized by a low transparenchymal pressure drop, typically 1 mm Hg. The present pape ...

Hydrocephalus is a brain disease wherein the ventricles dilate and compress the parenchyma towards the skull. It is primarily characterized by the disruption of the cerebrospinal fluid (CSF) flow within the ventricular system. Normal pressure hydrocephalus ...

Calculation of intracranial pressure in human brain using Darcy's and Biot's models

Jean-Marie Drezet, Kamal Shahim

Cerebrospinal fluid (CSF) is a colourless liquid that fills the ventricular space and serves several functions like buoyancy, chemical stability and protection. CSF is produced within the ventricles and partly by the ependyma cells. Part of it seeps toward ...

Cavitation influence on hydroacoustic resonance in pipe

François Avellan, Christophe Nicolet, Sébastien Alligné, Nicolas Ruchonnet

In pipe systems, pressure and flow fluctuations below cutoff frequency propagate as plane waves along pipes. Depending on the pipe length and propagation velocity, resonance leading to high amplitude pressure fluctuation may occur. At low pressure, cavitat ...

Response of an Embedded Block Impacted by High-Velocity Jets

Matteo Paolo Elia Antonio Federspiel

High-velocity plunging jets, issuing from ood release structures of dams, may result in scouring of the rocky riverbed and even endanger the foundation of the dams. Assessment of the scour extent is essential to ensure the safety of the dam and appurtenant ...

Implantable Antennas for Biomedical Applications

Francesco Merli

Since the introduction of implantable pacemakers in the early 1960s, implantable medical devices have become more and more interesting for healthcare services. Nowadays, the devices designed to monitor physiological data from inside the human body have gre ...
