  1. 1. Radiobiological investigations of proton and light ion therapy

    Författare :Nina Tilly; Michael Scholz; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiobiology; Monte Carlo method; Radiotherapy; high-energy instrumentation; Protons; Light ions; RBE; LET; Radiobiological models; Radiobiologi; medicinsk strålningsfysik; Medical Radiation Physics;

    Sammanfattning : During the last decade, the interest in proton and light ion beam therapy has increased considerably and several new centres are planned around the world. These particles have a large advantage due to their sharp physical dose distributions as compared to conventional radiotherapy beams. LÄS MER

  3. 2. Biological effects of high energy radiation and ultra high dose rates

    Författare :Björn Zackrisson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiobiology; 50 MV x-rays; 50 MeV electrons; in vitro; in vivo; RBE; OER; ultra high dose-rate; radiobiological models; model selection; models of stochastic processes;

    Sammanfattning : Recently a powerful electron accelerator, 50 MeV race-track microtron, has been taken into clinical use. This gives the opportunity to treat patients with higher x-ray and electron energies than before. Furthermore, treatments can be performed were the entire fractional dose can be delivered in parts of a second. LÄS MER

  4. 3. Improved dose response modeling for normal tissue damage and therapy optimization

    Författare :Magdalena Adamus-Górka; Bengt K. Lind; Anders Brahme; Panayiotis Mavroidis; Randall K. Ten Haken; Stockholms universitet; []
    Nyckelord :Normal tissue complications; radiobiological models; dose-response; volume effect; spinal cord; effective FSU size; medicinsk strålningsfysik; Medical Radiation Physics;

    Sammanfattning : The present thesis is focused on the development and application of dose response models for radiation therapy. Radiobiological models of tissue response to radiation are an integral part of the radiotherapeutic process and a powerful tool to optimize tumor control and minimize damage to healthy tissues for use in clinical trials.

  5. 4. From cell survival to dose response : modeling biological effects in radiation therapy

    Författare :Minna Wedenberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Radiobiological models;

    Sammanfattning : The main goal in curative radiation therapy is to eradicate the tumor while minimizing radiation-induced damage to normal tissue. Ions, including protons and carbon ions, are increasingly being used for cancer treatment. LÄS MER

  7. 5. Antenna Design, Radiobiological Modelling, and Non-invasive Monitoring for Microwave Hyperthermia

    Författare :Morteza Ghaderi Aram; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; UWB Antennas; Bio-Electromagnetics; Hyperthermia; Microwave Thermometry; Radiobiological Modeling;

    Sammanfattning : The death toll of cancers is on the rise worldwide and surviving patients suffer significant side effects from conventional therapies. To reduce the level of toxicity in patients treated with the conventional treatment modalities, hyperthermia (HT) has been investigated as an adjuvant modality and shown to be a potent tumor cell sensitizer for radio- and chemotherapy.
