Egalisation modale des salles avec des absorbeurs électroacoustiques

Hervé Lissek, Etienne Thierry Jean-Luc Rivet, Sami Driss Karkar

L’égalisation du champ sonore aux basses fréquences (égalisation modale) est un véritable défi dans les salles d’enregistrement ou dédiées aux systèmes audio. Les résonances modales conduisent à une distribution irrégulière en espace et en fréquence de l’é ...

Inter-operator Reliability of Magnetic Resonance Image-Based Computational Fluid Dynamics Prediction of Cerebrospinal Fluid Motion in the Cervical Spine

Nikolaos Stergiopoulos, Bryn Andrew Martin

For the first time, inter-operator dependence of MRI based computational fluid dynamics (CFD) modeling of cerebrospinal fluid (CSF) in the cervical spinal subarachnoid space (SSS) is evaluated. In vivo MRI flow measurements and anatomy MRI images were obta ...

Ferritin H gene deletion in the choroid plexus and forebrain results in hydrocephalus

Patrick Fraering, Claude André Schweizer

Ferritin H, the major iron storage protein, has essential functions in early embryonic development as well as in adult liver and intestine. To address the question whether ferritin H has similarly essential functions in the brain we used the Cre/loxP syste ...

The Impact of Spinal Cord Nerve Roots and Denticulate Ligaments on Cerebrospinal Fluid Dynamics in the Cervical Spine

Bryn Andrew Martin

Cerebrospinal fluid (CSF) dynamics in the spinal subarachnoid space (SSS) have been thought to play an important pathophysiological role in syringomyelia, Chiari I malformation (CM), and a role in intrathecal drug delivery. Yet, the impact that fine anatom ...

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 ...

Comparison of 4D Phase-Contrast MRI Flow Measurements to Computational Fluid Dynamics Simulations of Cerebrospinal Fluid Motion in the Cervical Spine

Nikolaos Stergiopoulos, Bryn Andrew Martin

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 ...

Magnetic resonance 4D flow analysis of cerebrospinal fluid dynamics in Chiari I malformation with and without syringomyelia

Bryn Andrew Martin

To analyse cerebrospinal fluid (CSF) hydrodynamics in patients with Chiari type I malformation (CM) with and without syringomyelia using 4D magnetic resonance (MR) phase contrast (PC) flow imaging. 4D-PC CSF flow data were acquired in 20 patients with CM ( ...

Bio Simulation of Brain Ventricle Dilation in Normal Pressure Hydrocephalus

Kamal Shahim

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 ...
