  1. 1. 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

  3. 2. Utvärdering av stråldoser för personal verksamma inom diagnostisk nuklearmedicin

    Kandidat-uppsats, Malmö universitet/Fakulteten för hälsa och samhälle (HS)

    Författare :Aya Mohammed; [2018]
    Nyckelord :Doshastighet; dose rate; PET; photon energy; deterministic; deterministiska; stochastic; stokastiska; fotonenergi; fingerdoser; finger doses; internal contamination; internkontamination;

    Sammanfattning : I nuklearmedicinska verksamheten utsätts personal för strålning på olika vis. Huvudsakligen genom administrering av radiofarmaka som injicering eller avfallshantering men även genom att befinna sig nära patient efter injektion av radiofarmaka. Med strålning finns risker för skador som förekommer i cellnivå. LÄS MER

  4. 3. NaCl pellets for improved dosimetry

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Lovisa Waldner; [2017]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : There is always a need to improve and develop new ways of estimating effective doses to people and environments that have been exposed to ionizing radiation. Dose monitoring is also important in hospitals and the nuclear industry. LÄS MER

  5. 4. TLD Measurements on Patients being treated with a Taylor Spatial Frame : Using Radiation from Na18F PET/CT Studies and from Naturally Occurring Radioisotopes

    Master-uppsats, Stockholms universitet/Fysikum

    Författare :Kousha Mirzadeh; [2014]
    Nyckelord :Taylor Spatial Frame; Thermoluminescent dosimeters; Tibia fracture; Bone remodeling; Na18F; PET CT; Bone seeking radionuclide;

    Sammanfattning : Background: In an ongoing study conducted at Karolinska Institutet & Karolinska University Hospital, Positron Emission Tomography (PET)/Computed Tomography (CT) scans are performed on patients with tibia fractures and deformations treated with Taylor Spatial Frames (TSFs) in order to monitor their bone remodeling progress. Each patients receive an administration of approximately 2 MBq/kg bodyweight of Na18F associated with PET scans on two sessions, six and twelve weeks after the attachment of the TSF. LÄS MER

  7. 5. Dosimetric Verification of Intensity Modulated Radiotherapy Treatment Plans with Radiographic Film

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Sonny La; [2004]
    Nyckelord :Strålterapi; Medicine and Health Sciences;

    Sammanfattning : "Intensity modulated radiation therapy (IMRT) is a fairly new modality in the treatment of cancer with radiotherapy. The original idea is Swedish and has existed for more than 20 years. But it is only in recent years that clinics have implemented the IMRT technique. LÄS MER
