  2. 1. Radiation therapy of upper gastrointestinal cancers with scanned proton beams : A treatment planning study

    Author : Gracinda Mondlane; Albert Siegbahn; Michael Gubanski; Iuliana Toma-Dasu; Crister Ceberg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Treatment planning; gastric cancer; liver metastases; photon beam therapy; proton beam therapy; dosimetric comparison; normal tissue complication probability; risk of radiation-induced secondary cancer; patient selection; Medical Radiation Physics; medicinsk strålningsfysik;

    Abstract : Proton beam therapy (PBT), using scanned beams, is an emerging modality used for the treatment of cancer. The clinical advantages of PBT, compared to commonly used photon beam therapy, have been demonstrated in different studies. READ MORE

  4. 2. Mathematical Modelling of Dose Planning in High Dose-Rate Brachytherapy

    Author : Björn Morén; Torbjörn Larsson; Åsa Carlsson Tedgren; Sebastiaan Breedveld; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Cancer is a widespread type of diseases that each year affects millions of people. It is mainly treated by chemotherapy, surgery or radiation therapy, or a combination of them. One modality of radiation therapy is high dose-rate brachytherapy, used in treatment of for example prostate cancer and gynecologic cancer. READ MORE

  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. 3D Verification of Dynamic and Breathing Adapted Radiotherapy using Polymer Gel Dosimetry

    Author : Sofie Ceberg; Malmö Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiotherapy; 3D verification; polymer gel;

    Abstract : Polymer gel dosimetry has been used since the 1990s, and several studies have shown that this detector system can be used for verification of static absorbed dose distributions in three dimensions (3D). Its unique properties, such as high resolution, normal tissue equivalence and independency of energy, field size and direction of the incident radiation, should also be advantageous for dosimetric verification of radiotherapy using today’s and tomorrow’s dynamic delivery techniques.

  7. 5. Quantitative imaging with PET : performance and applications of 76Br, 52Fe, 110mIn and 134La

    Author : Mark Lubberink; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; PET; Positron Emission Tomography; Quantitative Imaging; bromine; iron; indium; lanthanum; Onkologi; Oncology; Onkologi; Oncology; Onkologi;

    Abstract : The use of positron emission tomography (PET) has so far mainly been limited to a few nuclides with short half-lives such as 11C and 18F. Certain applications require nuclides with longer half-lives, such as 76Br and 52Fe. READ MORE
