  1. 6. Anterior cruciate ligament reconstruction using semitendinosus and gracilis autograft. Evaluation of the clinical outcome, radiographic findings, histology and biochemistry

    Författare :Martina Åhlén; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anterior Cruciate Ligament; hamstring tendon regeneration; biopsies; cartilage markers; inflammatory cytokines; MRI; strenght measurements;

    Sammanfattning : The present thesis focuses on different aspects of anterior cruciate ligament (ACL) reconstruction using hamstring tendon (HT) autografts. In Study I, two groups of patients were compared. LÄS MER

  3. 7. On bone quality and implant stability measurements

    Författare :Bertil Friberg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; early failures; titanium implants; jaw bone quality; jaw bone volume; cutting torque; implant stability; resonance frequency; one-stage surgery;

    Sammanfattning : In conjuction with placement of oral implants, the jaw bone quality assessment is mainly based on quantitative radiographic measures and the subjective opinion of the performing surgeon. While the primary implant stability is discussed in terms of the pre-set motor torque and the subjective hand-felt perception during final tightening of implants, the secondary stability is defined as the absence of implant mobility.

  4. 8. Radiographic imaging in relation to the mandibular third molar : tooth characteristics, modality choice, optimization, and absorbed dose

    Författare :Josefine Cederhag; Kristina Hellén-Halme; Henrik Lund; Malmö universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Radiographic imaging of the mandibular third molar (M3) is a valuable diagnostic tool. It provides information on tooth position, root morphology, and relations to surrounding anatomical structures that facilitates diagnosis and treatment planning. LÄS MER

  5. 9. Radiographic assessment of cup migration and wear after hip replacement

    Författare :Thomas Ilchmann; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; measurement; assessment; loosening; migration; wear; cup; Hip; arthroplasty; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

    Sammanfattning : Methods are needed for accurate measurement of acetabular cup migration and wear after hip replacement. The EBRA (Ein Bild Röntgen Analyse) method was recently introduced as a computerized method for radiographic assessment of acetabular cup migration. LÄS MER

  7. 10. Fast-Neutron Tomography using a Mobile Neutron Generator for Assessment of Steam-Water Distributions in Two-Phase Flows

    Författare :Peter Andersson; Staffan Jacobsson Svärd; Henrik Sjöstrand; Stephan Pomp; Ane Håkansson; Michael Österlund; Bernhard Ludewigt; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Void distribution; neutron tomography; plastic scintillator; transmission measurements; neutron detection; Applied Nuclear Physics; Tillämpad kärnfysik;

    Sammanfattning : This thesis describes the measurement technique of fast-neutron tomography for assessing spatial distributions of steam and water in two-phase flows. This so-called void distribution is of importance both for safe operation and for efficient use of the fuel in light water reactors, which compose the majority of the world’s commercial nuclear reactors.
