1. Probabilistic treatment planning based on dose coverage : How to quantify and minimize the effects of geometric uncertainties in radiotherapy
Abstract : Traditionally, uncertainties are handled by expanding the irradiated volume to ensure target dose coverage to a certain probability. The uncertainties arise from e.g. the uncertainty in positioning of the patient at every fraction, organ motion and in defining the region of interests on the acquired images. READ MORE

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

3. Beam Modelling for Treatment Planning of Scanned Proton Beams
Abstract : Scanned proton beams offer the possibility to take full advantage of the dose deposition properties of proton beams, i.e. the limited range and sharp peak at the end of the range, the Bragg peak. READ MORE

4. Mathematical Modelling of Dose Planning in High Dose-Rate Brachytherapy
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. On the use of radiography and radiation dose consideration in orthodontic treatment
Abstract : The aims of this thesis were to analyse the use of radiography and radiation risk associated with orthodontic treatment. Study I measured absorbed doses to radiosensitive organs in the head and neck in an anthropomorphic phantom head using thermo¬luminescent dosimeters (TLDs) from digital intra-oral and panoramic radiography.
