  2. 16. 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.

  4. 17. 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. 18. Optically Stimulated Luminescence for Retrospective Radiation Dosimetry. The Use of Materials Close to Man in Emergency Situations

    Author : Therése Geber-Bergstrand; Malmö Medicinsk strålningsfysik; []
    Keywords : Retrospective dosimetry; Emergency dosimetry; OSL;

    Abstract : If an accident or attack involving radiological or nuclear material were to happen, people from the general public would be at risk of exposure to ionising radiation. Unlike people working with ionising radiation, for whom level of exposure to radiation is constantly monitored with dosemeters, people from the general population do not wear dosemeters; thus, the dose estimations for these individuals must be performed using alternative methods.

  6. 19. Computational and experimental methods for imaging and dosimetry in 177Lu radionuclide therapy : Classical and novel gamma cameras

    Author : Daniel Roth; Lund Medicinsk strålningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Radionuklidterapi; [177Lu]Lu-DOTA-TATE; Gammakamera; Aktivitetskvantifiering; Dosimetri; CdZnTe; Monte Carlo; Radionuclide therapy; [177Lu]Lu-DOTA-TATE; Gamma camera imaging; Activity quantification; Dosimetry; CdZnTe; Monte Carlo;

    Abstract : Radionuclide therapy (RNT) is a form of radiotherapy that uses unsealed radioactive sources for the delivery of ionising radiation within a patient's body.Radiation dosimetry is not used routinely in all centres, and the RNT field can benefit from more data on pharmacokinetics and absorbed doses (ADs).

  7. 20. Realistic tissue dosimetry models using Monte Carlo simulations. Applications for radionuclide therapies

    Author : Erik Larsson; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; internal dosimetry; radionuclide therapy; Monte Carlo; small scale dosimetry;

    Abstract : Radionuclide therapy (RNT) is a generic term for treatment modalities that use a radionuclide labeled to a target-specific molecule. This so-called radiopharmaceutical accumulates in the target, where the ionizing radiation damages the cells. At sufficient levels of radiation, the cells cannot repair themselves. READ MORE
