1. 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

2. Development of analytical transport methods for biologically optimized light ion therapy
Abstract : A general objective in the treatment of cancer is to eradicate the tumour cells without inducing severe complications in healthy normal tissue. The use of light ions for radiation therapy increases the possibility to deliver tumour suicidal doses with very low probability of normal tissue injury, not least in cases where the target is unresectable, radioresistant and located to near organs at risk.

4. Absorbed dose and biological effect in light ion therapy
Abstract : Radiation therapy with light ions improves treatment outcome for a number of tumor types. The advantageous dose distributions of light ion beams en-able exceptional target conformity, which assures high dose delivery to the tumor while minimizing the dose to surrounding normal tissues.

5. Developing and evaluating dose calculation models for verification of advanced radiotherapy
Abstract : A prerequisite for modern radiotherapy is the ability to accurately determine the absorbed dose (D) that is given to the patient. The subject of this thesis has been to develop and evaluate efficient dose calculation models for high-energy photon beams delivered by linear accelerators. READ MORE
