  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. 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

  4. 3. Protons, other Light Ions, and 60Co Photons : Study of Energy Deposit Clustering via Track Structure Simulations

    Författare :Gloria Bäckström; Anders Ahnesjö; Nina Tilly; José M. Fernández-Varea; Niels Bassler; Uppsala universitet; []
    Nyckelord :Proton; light ion; Co-60 photon; track structure Monte Carlo code; clustering patterns of energy deposit; RBE; Medicinsk radiofysik; Medical Radiophysics;

    Sammanfattning : Radiotherapy aims to sterilize cancer cells through ionization induced damages to their DNA whilst trying to reduce dose burdens to healthy tissues. This can be achieved to a certain extent by optimizing the choice of radiation to treat the patient, i.e. the types of particles and their energy based on their specific interaction patterns.

  5. 4. Beam Modelling for Treatment Planning of Scanned Proton Beams

    Författare :Peter Kimstrand; Bengt Glimelius; Erik Traneus; Nina Tilly; Anders Ahnesjö; Thomas Bortfeld; Uppsala universitet; []
    Nyckelord :Radiation sciences; proton therapy; treatment planning; beam modelling; dose calculation; Monte Carlo; Strålningsvetenskap;

    Sammanfattning : Scanned proton beams offer the possibility to take full advantage of the dose deposition properties of proton beams, i.e. the limited range and sharp peak at the end of the range, the Bragg peak. LÄS MER
