  1. 16. 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

  3. 17. Rapid Preparation of Soft Tissue for X-ray Virtual Histology

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Filip Lagerqvist; [2022]
    Nyckelord :Phase-contrast computed tomography; fixation; fixation time; image segmentation; tumor resection margin;

    Sammanfattning : When removal of primary tumors is performed by surgery, the surgeon andthe patient would benefit from using intraoperative feedback to evaluate thetumor resection margin. If intraoperative feedback is not provided there isadditional risk of treatment of the tumor. LÄS MER

  4. 18. High resolution x-ray imaging by measuring the induced charge distribution

    Master-uppsats, KTH/Fysik

    Författare :Zihui Jin; [2022]
    Nyckelord :Computed tomography; photon-counting detector; silicon; spatial resolution; Datortomografi; fotonräknande detektor; kisel; spatial upplösning;

    Sammanfattning : Computed tomography (CT) is a medical imaging technique used to create cross-section images of human bodies based on x-rays. The emerging photon-counting CT detector shows several advantages compared with the traditional energy integrating detector. LÄS MER

  5. 19. Typiska skador relaterade till barnmisshandel, Vid konventionell och DT-röntgen

    Kandidat-uppsats,

    Författare :Dalal Fakhruldeen; Alaa Saadi; [2021-06-08]
    Nyckelord :Child abuse; Skeletal survey; fractures; Radiology; Radiographer; Radiography; computed tomography;

    Sammanfattning : Bakgrund: Barnmisshandel är ett samhällsproblem som har ökat över tiden, och kan vara fysiskt, psykiskt eller sexuellt. Den fysiska misshandeln innefattar oftast skelett- och hjärnskador vilka utreds med hjälp av röntgenundersökning. LÄS MER

  7. 20. EVALUATION OF RADIATION DOSES USING CONE BEAM COMPUTED TOMOGRAPHY IN ENDOVASCULAR AORTIC REPAIR AND SCOLIOSIS PROCEDURES

    Master-uppsats,

    Författare :Louise Strandberg; [2021-04-06]
    Nyckelord :Medical physics; Cone beam CT; CT; EVAR; scoliosis; radiation dose; effective dose;

    Sammanfattning : Purpose: The study includes the two areas, vascular surgery and orthopedics, and focuses on endovascular aortic aneurysm repair (EVAR) and scoliosis procedures. EVAR procedures contribute to a high radiation dose to the patient and for scoliosis procedures, it is often young girls that are undergoing surgery. LÄS MER
