  1. 11. Patientens upplevelse av oro i samband med en datortomografiundersökning med intravenös kontrast : En deskriptiv enkätstudie

    M1-uppsats, Uppsala universitet/Radiologi

    Författare :Hawnaz Karimi; Johannes Romsi; [2022]
    Nyckelord :Kontrastmedel; patientens oro; information; kallelse; biverkningar;

    Sammanfattning : Background: Examinations with computer tomography (CT) with iodinated contrast agents has become more common. The examination can cause anxiety for the patient and variying side effects has been observed. The preparatory information concerning contrast agents is at the same time short. LÄS MER

  3. 12. Application of ERT for Quality Assurance in Jet Grouting Columns; A development of an alternative quality control

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Författare :Edvin Nilsagård; Rebecka Knutsson; [2022]
    Nyckelord :ert; jet grouting; quality control; pygimli; res2dinv; resistivity; Technology and Engineering;

    Sammanfattning : With the increased urbanization major cities are facing, expansion of larger facilities and households are inevitable. Expansion means larger areas of the surface needs to be used where the risk of varying subsurface soil properties increases with larger surface areas. LÄS MER

  4. 13. Optimization of an advanced algorithm for bone imaging

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Adam Mrozek; [2022]
    Nyckelord :osteoporosis; optimization; programming; engineering; X-ray; bone; mineral density; speed; faster; projection; MATLAB; C ; Technology and Engineering;

    Sammanfattning : Fracture risk in osteoporosis is increased and osteoporosis is the most common metabolic bone disease and treatment is expensive. Osteoporosis is diagnosed by measuring Bone Mineral Density (BMD), which does not consider other factors such as bone geometry or architecture. LÄS MER

  5. 14. An Application of Channelized Hotelling Observer for Optimization of CT Scanning Protocols

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Yuting Wang; [2022]
    Nyckelord :;

    Sammanfattning : Low contrast detection tasks like detecting a lesion in an image are of high importance in medical image diagnostics. If performed by human observers, the results are subjective, and the reproducibility is limited. LÄS MER

  7. 15. Assessment of hip deformities during childhood: a combined approach of Machine Learning and Finite Element Analysis

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Klara Eriksson; Jonna Fahrman; [2022]
    Nyckelord :Biomechanics; Hip joint; Cartilage; Osteoarthritis; Machine learning; Finite element analysis; Technology and Engineering;

    Sammanfattning : Osteoarthritis is a degenerative disease that will cause pain and stiffness in the joint if not treated. One cause of early osteoarthritis in the hip joint is pediatric hip deformities. Hip deformities can occur in different stages of childhood and cause the bones to be misshapen or the hip joint to be dislocated. LÄS MER
