  2. 1. Development of a Whole Body Atlas for Radiation Therapy Planning and Treatment Optimization

    Author : Sharif Qatarneh; Anders Brahme; Bengt Lind; Anders Ahnesjö; Stockholms universitet; []
    Keywords : 3D whole body atlas; lymph node topography; matching transformation; radiation therapy planning; radiobiological optimization; segmentation; target volume definition; medicinsk strålningsfysik; Medical Radiation Physics;

    Abstract : The main objective of radiation therapy is to obtain the highest possible probability of tumor cure while minimizing adverse reactions in healthy tissues. A crucial step in the treatment process is to determine the location and extent of the primary tumor and its loco regional lymphatic spread in relation to adjacent radiosensitive anatomical structures and organs at risk.

  5. 3. Cutaneous malignant melanoma aspects of prognostic factors and time : trends in a Swedish population

    Author : Eva Månsson-Brahme; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Melanoma; incidence; prognostic factors; survival; mortality; trends; familial; prevention;

    Abstract : One of the aims of this thesis was to assess the possible impact of primary and secondary preventive activities in the population of Stockholm-Gotland with the objective to reduce the incidence and mortality from cutaneous melanoma. Another aim was to investigate whether thin melanomas and hereditary melanomas represent separate biologic entities. READ MORE

  6. 4. Development of improved radiation therapy techniques using narrow scanned photon beams

    Author : Björn Andreassen; Anders Brahme; Håkan Danared; Roger Svensson; Antony Lomax; Stockholms universitet; []
    Keywords : IMRT; Scanned photon beams; PET-CT treatment verification; Monte Carlo; NATURAL SCIENCES; NATURVETENSKAP; Medical Radiation Physics; medicinsk strålningsfysik;

    Abstract : The present thesis is focused on the development and application of narrow scanned high energy photon beam for radiation therapy. The introduction of physically and biologically optimized intensity modulated radiation therapy (IMRT) requires a flexible and accurate dose delivery method to maximize the treatment outcome.

  7. 5. Verification of high energy photon therapy based on PET/CT imaging of photonuclear reactions

    Author : Sara Janek Strååt; Anders Brahme; Cathrine Jonsson; Iuliana Dasu; Sibylle Ziegler; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Photonuclear reactions; PET CT treatment verification; High-energy photon therapy; Medical Radiation Physics; medicinsk strålningsfysik;

    Abstract : For classical and intensity modulated radiation therapy of deep-seated tumors, high-energy photons are the optimal radiation modality from an integral dose point of view. By using narrow scanned beams the treatment outcome can be improved substantially by delivering biologically optimized intensity modulated distributions often with sharp dose gradients. READ MORE
