  1. 6. Brain injury biomechanics in closed-head impact : studies on injury epidemiology, tolerance criteria, biomechanics and traffic injury prevention

    Författare :David Viano; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Closed-head impact; brain injury; biomechanics; injury mechanisms; tolerance criteria; epidemiology; and primary prevention.;

    Sammanfattning : Permanent disability from traumatic brain injury is a devastating consequence of traffic crashes. Injury prevention is a fruitful approach to reduce the incidence and severity of disabling brain injury. LÄS MER

  3. 7. Physical Modeling of Brain and Head Kinematics

    Författare :Johan Ivarsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; brain injury; skull base; rotational acceleration; physical models; lateral ventricles; head kinematics; padding materials; sulci; free motion headform; brain kinematics;

    Sammanfattning : The development of head injury criteria and countermeasures for head protection requires understanding of how different factors affect brain and head kinematics. In this thesis, 2D physical models of the human head were developed and used to evaluate how various factors affect brain kinematics during angular head kinematics. LÄS MER

  4. 8. 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

  5. 9. Traumatic Brain Injuries: Animal Experiments and Numerical Simulations to Support the Development of a Brain Injury Criterion

    Författare :Jacobo Antona; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; traumatic brain injuries; traffic safety; concussions; animal experiments; finite element method;

    Sammanfattning : Traumatic Brain Injuries (TBIs) account for about half of the 1 300 000 annual traffic related deaths and the 50 000 000 injuries worldwide. The burden of TBI is ethically unacceptable and economically unsustainable. LÄS MER

  7. 10. 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
