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

2. Investigations on the application of a microtron accelerator for radiation therapy
Sammanfattning : .... LÄS MER
3. Cutaneous malignant melanoma aspects of prognostic factors and time : trends in a Swedish population
Sammanfattning : 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. LÄS MER
4. Development of improved radiation therapy techniques using narrow scanned photon beams
Sammanfattning : 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. LÄS MER
5. Verification of high energy photon therapy based on PET/CT imaging of photonuclear reactions
Sammanfattning : 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. LÄS MER
