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

    Author : Per Munck af Rosenschöld; Lund Medicinsk strålningsfysik; []
    Keywords : 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;

    Abstract : 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). READ MORE

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

    Author : Fredrik Nordström; Malmö Medicinsk strålningsfysik; []
    Keywords : 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;

    Abstract : 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.

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

    Author : Elin Cederkrantz; Göteborgs universitet; []
    Keywords : 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;

    Abstract : 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.

  6. 4. The Importance of Dosimetry and Radiobiology in Nuclear Medicine : Quantitative methods and modelling

    Author : Anna Stenvall; Lund Medicinsk strålningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear medicine; radionuclide therapy; radiopharmaceutical therapy; dosimetry; Monte Carlo modelling; radiobiology; ; γH2AX; DOTA-TATE; PET; SPECT;

    Abstract : Nuclear medicine uses radioactive pharmaceuticals for diagnostic or therapeutic purposes. The ionizing radiation emitted from the radiopharmaceutical is partially absorbed within the patient's body and internal dosimetry is the method to estimate the absorbed dose to a tumour or risk organ.
