  4. 12. Interlaced proton grid therapy: development of an innovative radiation treatment technique

    Author : Thomas Henry; Irena Gudowska; Tony Lomax; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; proton therapy; grid therapy; spatially fractionated therapy; interlacing; Medical Radiation Physics; medicinsk strålningsfysik;

    Abstract : Spatially fractionated radiotherapy, also known as grid therapy (GRID), has been used for more than a century to try to treat several kinds of lesions. Yet, the grid technique remains a relatively unknown and uncommon treatment modality nowadays. READ MORE

  5. 13. Comparative study of Radiation Therapy of Targets in the Upper Abdomen with Photon- or Scanned Proton-beams

    Author : Gracinda Mondlane; Albert Siegbahn; Michael Gubanski; Iuliana Toma-Dasu; Crister Ceberg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; photon radiotherapy; proton beam radiotherapy; gastric cancer; liver metastases; Medical Radiation Physics; medicinsk strålningsfysik;

    Abstract : Recently, there has been an increase in the number of proton beam therapy (PBT) centers operating worldwide. For certain cases, proton beams have been shown to provide dosimetric and radiobiological advantages when used for cancer treatment, compared to the regular photon-beam based treatments. READ MORE

  6. 14. Techniques for the increased utilization of dose response variability in proton therapy

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

    Abstract : 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). READ MORE

  7. 15. Bits and Pieces for the Nuclear Puzzle - Exploring light exotic nuclei with radioactive ion beams

    Author : Ronja Thies; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ISOLDE; GSI; FAIR; R3B; Neutron-rich nuclei; Radioactive Beams;

    Abstract : Atomic nuclei are a fascinating case of many-body systems governed by quantum behaviour. This fact and the complex nuclear interaction are reasons why there is not yet a complete theory describing all atomic nuclei. Both experimental and theoretical efforts are needed to change this situation. READ MORE
