  2. 1. Dosimetric effects of breathing motion in radiotherapy

    Author : Anneli Edvardsson; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; radiotherapy; breathing motion; DIBH; interplay effects; VMAT; proton therapy; breast cancer; Hodgkin’s lymphoma; liver; dosimetry; treatment planning; medical physics;

    Abstract : The goal of radiotherapy is to deliver a homogeneous high dose of radiation to a tumour while minimising the dose to the surrounding healthy tissue. To achieve this, increasingly advanced treatment techniques, such as volumetric modulated arc therapy (VMAT) and proton therapy, have been developed. READ MORE

  4. 2. Radiation and matter: how do they play with each other?

    Author : Davide Mancusi; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; heavy ions; models; transport codes; Boltzmann equation; Monte Carlo; radioprotection in space; radiotherapy; nuclear reactions;

    Abstract : The propagation of radiation is affected by the presence of matter; at the same time, the physicochemical properties of matter are modified by the passage of radiation. The interplay of radiation and matter is of crucial importance in many modern applications: accelerated heavy ions, in particular, can be used in radiotherapeutical treatments of some cancers; moreover, they are present in the space radiation environment and represent a serious threat to the health of spaceship crews and to the functionality of electronic equipment on board.

  5. 3. 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. 4. Systematic Modular Approaches to Reveal DNA Damage Responses in Mammalian Cells

    Author : J. Peter Svensson; Ingela Turesson; Jean Bourhis; Uppsala universitet; []
    Keywords : Molecular biology; gene expression profiling; DNA damage; network; cancer; ionizing radiation; cisplatin; Molekylärbiologi;

    Abstract : Cancer therapy operates by inflicting damage in malignant cells. The most lethal target is the genomic DNA. As a single double strand DNA break has the potential to kill the cell, mechanisms have evolved to detect and block propagation of the damage. READ MORE
