  1. 1. Three-dimensional guidance for Endovascular Aortic Repair

    Författare :Giasemi Koutouzi; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anatomy deformation; CBCT; EVAR; image fusion; image guidance; image registration;

    Sammanfattning : Image fusion (IF) of preoperative computed tomography (CT) with intraoperative cone-beam CT (CBCT) is a potentially powerful tool for guidance during endovascular aortic repair (EVAR). It may improve intraoperative anatomic visualization and reduce doses of radiation and contrast medium. LÄS MER

  3. 2. Tibia stress fractures in athletes : an investigation of possible predisposing factors

    Författare :Ingrid Ekenman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Stress fracture; tibia; overuse injuries; biomechanics; strain; trait characteristics; running; exercise dependency; type A behavior; intrinsic factors; extrinsic factors; local deformation; in vivo; sports; muscle; anatomy.;

    Sammanfattning : This study indicated that posteromedial and anterior tibia stress fractures are two entities with different etiology, pathoanatomy and natural course. In both cases clinical examination and bone scintigram were conclusive for the diagnosis. LÄS MER

  4. 3. Guidance and Visualization for Brain Tumor Surgery

    Författare :Filipe Miguel Maria Marreiros; Örjan Smedby; Sandro Rossitti; Karin Wårdel; Anders Ynnerman; Ole Jacob Elle; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Image guidance and visualization play an important role in modern surgery to help surgeons perform their surgical procedures. Here, the focus is on neurosurgery applications, in particular brain tumor surgery where a craniotomy (opening of the skull) is performed to access directly the brain region to be treated. LÄS MER

  5. 4. Rib and Thoracic Response in Frontal Car Crashes: A Study Using a Finite Element Human Body Model

    Författare :Manuel Mendoza-Vazquez; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Frontal crash; THUMS; thoracic injury criteria; Finite Element; Human Body Model; rib fracture;

    Sammanfattning : Traditionally, restraint systems have been evaluated with Anthropomorphic Test Devices (ATDs) and the thoracic injury criteria have been based on parameters assessed using ATDs, such as chest compression. ATDs have limitations since they are only a gross representation of the human body. LÄS MER
