  1. 1. Radiobiological studies with low energy ionizing radiation - dosimetric aspects

    Författare :Gustav Grafström; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; low energy; Radiobiology; dosimetry; cell model; Radiofarmaceutisk teknik; Radiopharmaceutical technology; radiobiologi; Nukleärmedicin; radiobiology; Nuclear medicine; animal model;

    Sammanfattning : Background: During the last 20 years both in vitro and in vivo models have been developed for studies of the cell killing characteristics of low energy electrons, e.g. Auger electrons. This thesis deals with radiobiological effects of radiation from indium isotopes in V79 cells in vitro (Paper I-III) and the rat testis in vivo (Paper IVV). LÄS MER

  3. 2. The Importance of Dosimetry and Radiobiology in Nuclear Medicine : Quantitative methods and modelling

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

    Sammanfattning : 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. 3. Techniques for the increased utilization of dose response variability in proton therapy

    Författare :Erik Almhagen; Anders Ahnesjö; Alexandru Dasu; Nina Tilly; Oliver Jäkel; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; RBE; Radiobiology; Proton Therapy; Dose Painting; Head and Neck Cancer; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Particle therapy is a form of radiation therapy in which protons and heavier ions are used, as opposed to photons in conventional radiation therapy. The biological effectiveness of particles compared to photons is often quantified as relative biological effectiveness (RBE). LÄS MER

  5. 4. Improving the therapeutic ratio of stereotactic radiosurgery and radiotherapy

    Författare :Bahram Andisheh; Bengt Lind; John Hopewell; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optimization; stereotactic radiosurgery; stereotactic radiotherapy; radiobiology; modeling; Medical Radiation Physics; medicinsk strålningsfysik;

    Sammanfattning : New methods of high dose delivery, such as intensity modulated radiation therapy (IMRT), stereotactic radiation therapy (SRT) or stereotactic radiosurgery (SRS), hadron therapy, tomotherapy, etc., all make use of a few large fractions. LÄS MER

  7. 5. Optimization of brachytherapy for cervical cancer using inverse planning algorithms

    Författare :Lucilio dos Santos Matias; Iuliana Toma-Dasu; Brígida da Costa Ferreira; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Brachytherapy; treatment planning optimization; IPSA; HIPO; radiobiology; complicationfree; medicinsk strålningsfysik; Medical Radiation Physics;

    Sammanfattning : Carcinoma of the cervix is a global problem. Brachytherapy (BT) is one of the mainradiation therapy components used in the management of cervical cancer. LÄS MER
