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

    Author : Nina Tilly; Michael Scholz; Stockholms universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Antenna Design, Radiobiological Modelling, and Non-invasive Monitoring for Microwave Hyperthermia

    Author : Morteza Ghaderi Aram; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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.

  5. 3. Contouring variability in radiosurgery - dosimetric and radiobiological implications

    Author : Helena Sandström; Iuliana Toma-Dasu; Mike Partridge; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Medical Radiation Physics; medicinsk strålningsfysik;

    Abstract : The use of Stereotactic Radiation Therapy (SRT) employing one large fraction of radiation, as in stereotactic radiosurgery (SRS), or few fractions of high doses, has continuously increased due to the technical development and the progress in dose delivery complemented by the positive clinical experience. The success of stereotactic radiation therapy depends on many clinical, dosimetric and radiobiological factors. READ MORE

  6. 4. Radiobiological studies with low energy ionizing radiation - dosimetric aspects

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

    Abstract : 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). READ MORE

  7. 5. Determination and use of radiobiological response parameters in radiation therapy optimization

    Author : Panayiotis Mavroidis; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Radiotherapy optimization; tumour control; normal tissue complications; radiobiological treatment planning; biological models; dose-response parameters;

    Abstract : Optimization of radiation therapy is critically dependent on the use of patient related information. For this reason, radiobiological models describing the dependence of tumour and normal tissue responses on the irradiated volume and the dose-time-fractionation schedule should be introduced.
