  3. 7. 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

  4. 8. Towards improved motorcycle helmet test methods for head impact protection : Using experimental and numerical methods

    Författare :Shiyang Meng; Svein Kleiven; Peter Halldin; Mazdak Ghajari; KTH; []
    Nyckelord :Head Injuries; Helmet; Injury Prevention; Motorcycle; Test Standard; Finite Element Method; Applied Medical Technology; Tillämpad medicinsk teknik;

    Sammanfattning : Head injury is the leading cause of death and major trauma for users of powered two-wheelers (PTWs). Helmet use can prevent and reduce head injuries when a crash is inevitable. However, today’s motorcycle helmets do not protect equally against all types of head injuries. LÄS MER

  5. 9. 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.

  7. 10. Understanding Boundary Conditions for Brain Injury Prediction : Finite Element Analysis of Vulnerable Road Users

    Författare :Victor S. Alvarez; Svein Kleiven; Peter Halldin; Ciaran Simms; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Brain injuries; Vulnerable Road Users; windscreen impacts; Finite Element Analysis; pedestrian accidents; cycling accidents; pediatric neck; Applied Medical Technology; Tillämpad medicinsk teknik;

    Sammanfattning : Vulnerable road users (VRUs) are overrepresented in the statistics on severe and deadly injuries in traffic accidents, most commonly involving the head. The finite element (FE) method presents the possibility to model complex interactions between the human body and vehicles in order to better understand the injury mechanisms. LÄS MER
