1. Radiation therapy of upper gastrointestinal cancers with scanned proton beams : A treatment planning study
Sammanfattning : 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. LÄS MER
2. Development and application of composite energy deposition kernels for photon therapy planning
Sammanfattning : In recent years, the use of optimization algorithms in radiation therapy planning has increased dramatically. All optimization algorithms as well as most modern implementations of conventional therapy planning, use energy deposition kernels as a fundamental part of the calculations. LÄS MER
3. Monte Carlo particle transport codes for ion beam therapy treatment planning : Validation, development and applications
Sammanfattning : External radiotherapy with proton and ion beams needs accurate tools for the dosimetric characterization of treatment fields. Monte Carlo (MC) particle transport codes, such as FLUKA and GEANT4, can be a valuable method to increase accuracy of dose calculations and to support various aspects of ion beam therapy (IBT), such as treatment planning and monitoring.

4. Indirect Radiohalogenation of Targeting Proteins : Labelling Chemistry and Biological Characterisation
Sammanfattning : In about half of all newly diagnosed cancer cases, conventional treatment is not adequately curative, mainly due to the failure of conventional techniques to find and kill residual cells and metastases, which might consist of only a few malignant cells, without causing unacceptable complications to healthy tissue. To solve the problem a more selective delivery of cytotoxic substances to tumour cells is needed. LÄS MER
5. Wastewater discharges and microbial variability in a surface water source
Sammanfattning : Planning for drinking-water safety in surface waters includes a systematic assessment of hazards in the catchment, and microbial contamination is considered a major health risk. The aim of this thesis was to identify and characterize microbial hazardous events reported for River Göta älv, Sweden. LÄS MER
