1. 1. Finite Element and Neuroimaging Techniques toImprove Decision-Making in Clinical Neuroscience

   Författare :Xiaogai Li; Svein Kleiven; Hans von Holst; Bernhard A Schrefler; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traumatic brain injury; Intracranial Pressure; Brain edema; Gravitational force; Finite Element Model; Poroelastic parameter; Decompressive craniotomy; Image registration; Water content; Strain level; Diffusion Weighted Imaging;

   Sammanfattning : Our brain, perhaps the most sophisticated and mysterious part of the human body, to some extent, determines who we are. However, it’s a vulnerable organ. When subjected to an impact, such as a traffic accident or sport, it may lead to traumatic brain injury (TBI) which can have devastating effects for those who suffer the injury. LÄS MER

3. 2. Definition of axonal injury tolerances across scales : A computational multiscale approach

   Författare :Annaclaudia Montanino; Svein Kleiven; Alessandra Villa; Xiaogai Li; Kacy Cullen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traumatic Brain Injury; Axonal Injury; Mechanoporation; Multiscale;

   Sammanfattning : Traumatic brain injury (TBI) is today regarded as a global health challenge. Revealing how external mechanical loads translate into tissue and cellular damage is necessary, not only for the development of better preventive measures, but also for the definition of treatments that could spare the patients from suffering TBI's devastating consequences.

4. 3. Electroosmosis Based Treatment Approach for Cerebral Edema

   Författare :Teng Wang; Xiaogai Li; Svein Kleiven; Tiit Illimar Mathiesen; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cerebral edema; electroosmosis based treatment; finite element head model; electroosmotic flow; Technology and Health; Teknik och hälsa;

   Sammanfattning : Cerebral edema characterized as an abnormal accumulation of excess fluid in the intracellular or extracellular spaces has not been treated effectively despite aggressive treatments. As a result, cerebral edema often leads to intracranial pressure (ICP) elevation with potentially severe consequences unless treated effectively. LÄS MER

5. 4. Evaluation of Fluid-Structure Interaction and Biofidelity of Finite Element Head Models

   Författare :Zhou Zhou; Svein Kleiven; Xiaogai Li; David Meaney; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied Medical Technology; Tillämpad medicinsk teknik;

   Sammanfattning : Traumatic brain injury is a critical public health issue. Finite element (FE) head models are valuable instruments to explore the causal pathway from mechanical insult to resultant brain injury. Intracranial fluid-structure interaction (FSI) and biofidelity evaluation are two fundamental aspects of FE head modeling. LÄS MER
