  1. 1. Development of Monte Carlo track structure simulations for protons and carbon ions in water

    Author : Thiansin Liamsuwan; Hooshang Nikjoo; Shuzo Uehara; David Liljequist; Michael Dingfelder; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Radiation track structure; Monte Carlo simulations; interaction cross sections; classical trajectory Monte Carlo CTMC method; microdosimetry; ion beams; Medical Radiation Physics; medicinsk strålningsfysik;

    Abstract : The goal of radiation therapy is to eradicate tumour cells while minimising radiation dose to healthy tissues. Ions including protons and carbon ions have gained increasing interest for cancer treatment. READ MORE

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

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

    Abstract : 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.

  3. 3. Micro/nanometric Scale Study of Energy Deposition and its Impact on the Biological Response for Ionizing Radiation : Brachytherapy radionuclides, proton and carbon ion beams

    Author : Fernanda Villegas Navarro; Anders Ahnesjö; Carmen Villagrasa; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ionizing radiation; Monte Carlo track structure code; Microdosimetric spread; Energy deposition clustering; RBE; Medicinsk radiofysik; Medical Radiophysics;

    Abstract : Research in radiotherapy for cancer treatment focuses on finding methods that can improve the compromise between tumour cell inactivation versus damage to the surrounding healthy tissue. As new radiation modalities such as proton therapy become accessible for everyday clinical practice, a better understanding of the variation in biological response of the tumour and healthy tissues would improve treatment planning to achieve optimal outcome.

  4. 4. Absorbed dose and biological effect in light ion therapy

    Author : Malin Hollmark; Irena Gudowska; Oliver Jäkel; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Light ion therapy; absorbed dose calculation; analytical pencil beam model; Monte Carlo; radiobiological modeling; Radiological physics; Radiofysik; medicinsk strålningsfysik; Medical Radiation Physics;

    Abstract : Radiation therapy with light ions improves treatment outcome for a number of tumor types. The advantageous dose distributions of light ion beams en-able exceptional target conformity, which assures high dose delivery to the tumor while minimizing the dose to surrounding normal tissues.

  5. 5. Modeling of dose and sensitivity heterogeneities in radiation therapy

    Author : Kristin Wiklund; Bengt K. Lind; Iuliana Toma-Dasu; Marco Zaider; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Monte Carlo simulations; Tumor control probability; Modeling; Beam characterization; Medical Radiation Physics; medicinsk strålningsfysik;

    Abstract : The increased interest in the use of light ion therapy is due to the high dose conformity to the target and the dense energy deposition along the tracks resulting in increased relative biological effectiveness compared to conventional radiation therapy. In spite of the good clinical experience, fundamental research on the characteristics of the ion beams is still needed in order to be able to fully explore their use. READ MORE
