  2. 1. Radiotherapy for head and neck cancer : costs and benefits of time, dose and volume

    Author : Karin Söderström; Björn Zackrisson; Werner Dubrowsky; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiotherapy; head and neck cancer; adjuvant treatment; accelerated fractionation; biomedicinsk strålningsvetenskap; Biomedical Radiation Science;

    Abstract : Background In the treatment of head and neck cancers (HNCs), radiotherapy (RT) has the advantage of organ preservation compared to surgery. However, treatment toxicities associated with RT can affect important functions for everyday life, both in the acute and late stage. READ MORE

  5. 3. Quality assurance for magnetic resonance imaging (MRI) in radiotherapy

    Author : Mary Adjeiwaah; Tufve Nyholm; Anders Garpebring; Joakim Jonsson; Sofie Ceberg; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; magnetic resonance imaging; MRI; radiotherapy; RT; geometric distortions; magnetic susceptibility; B0 maps; quality assurance; radiofysik; radiation physics;

    Abstract : The use of Magnetic Resonance Imaging (MRI) in the radiotherapy (RT) treatment planning workflow is increasing. MRI offers superior soft-tissue contrast compared to Computed Tomography (CT) and therefore improves the accuracy in target volume definitions. READ MORE

  7. 5. Integration of MRI into the radiotherapy workflow

    Author : Joakim Jonsson; Tufve Nyholm; Mikael Karlsson; Magnus Karlsson; Uulke van der Heide; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; magnetic resonance imaging; radiotherapy; treatment planning; image registration; workflow; radiofysik; radiation physics;

    Abstract : The modern day radiotherapy treatments are almost exclusively based on computed tomography (CT) images. The CT images are acquired using x-rays, and therefore reflect the radiation interaction properties of the material. READ MORE
