  1. 1. Mixed Beam Dosimetry - From Reactor Core to BNCT Patient

    Detta är en avhandling från Per Munck af Rosenschöld, Dept. of Radiation Physics, Klinikg. 7, 22185 LUND, SWEDEN

    Författare :Per Munck af Rosenschöld; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; BNCT; dosimetry; radiotherapy; mixed beam; quality assurance; in vivo dosimetry; Monte Carlo; ionization chamber; foil activation; MCNP; beam quality correction factor; photon transmission.; Nukleärmedicin; radiobiology; Nuclear medicine; radiobiologi; Radiofarmaceutisk teknik; Radiopharmaceutical technology;

    Sammanfattning : Accurate radiation dosimetry is of paramount importance in order to ensure safe delivery of radiotherapy, and for the possibility of meaningful evaluation of clinical trials, as the radiation absorbed dose is correlated to tissue response. The aim of the studies described in this thesis was to investigate and devise novel approaches to mixed beam dosimetry in boron neutron capture therapy (BNCT). LÄS MER

  2. 2. Quality Assurance in Radiotherapy - Development and evaluation of new tools for improved patient safety

    Detta är en avhandling från Lund University

    Författare :Fredrik Nordström; [2012]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; monitor unit verification; in vivo dosimetry; real-time verification; gel dosimetry; 4D dosimetry; IMRT; VMAT; data integrity; radiotherapy; Quality assurance;

    Sammanfattning : Preparation for radiotherapy is a complex procedure that involves many different technologies and groups of professionals. The rapid development and introduction of new technologies throughout the last decade have made it possible to deliver highly conformal, individually-shaped dose distributions with high accuracy.

  3. 3. Pharmacokinetics and dosimetry in intraperitoneal radioimmunotherapy with 211At

    Detta är en avhandling från Göteborg : University of Gothenburg

    Författare :Elin Cederkrantz; Göteborgs universitet.; Gothenburg University.; [2014]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; astatine-211; radioimmunotherapy; alpha-emitter; ovarian cancer; MX35; pharmacokinetics; dosimetry; effective dose;

    Sammanfattning : The prognosis for patients diagnosed with disseminated cancer is often poor. Radioimmunotherapy (RIT) is a new approach to treat disseminated disease. The aim is to target tumor cells with monoclonal antibodies (mAbs) labeled with radionuclides which release cytotoxic particle radiation upon decay. The radionuclide 211At, with half-life 7. LÄS MER

  4. 4. Luminescence Spectroscopy For Biomedical Applications

    Detta är en avhandling från Department of Physics, Lund University

    Sammanfattning : This work presents optical methods utilizing visible light for characterization of biological tissue during diagnostics and treatment processes. The main aim has been to improve the therapeutic outcome of treatment modalities in in vivo studies. LÄS MER

  5. 5. Evaluation of absorbed dose and image quality in mammography

    Detta är en avhandling från Department of Physics, Lund University

    Författare :Bengt Hemdal; [2009]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; optically stimulated luminescence; radioluminescence; in vivo dosimetry; dose reduction; dose protocol; average glandular dose; absorbed dose; Breast cancer; mammography; Monte Carlo; image quality; image quality criteria; contrast-detail phantom;

    Sammanfattning : Mammography refers to the X-ray examination of the human breast, and is considered the single most important diagnostic tool in the early detection of breast cancer, which is by far the most common cancer among women. There is good evidence from clinical trials, that mammographic screening can reduce the breast cancer mortality with about 30%. LÄS MER
