6. 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

7. Multicriteria optimization for managing tradeoffs in radiation therapy treatment planning
Abstract : Treatment planning for radiation therapy inherently involves tradeoffs, such as between tumor control and normal tissue sparing, between time-efficiency and dose quality, and between nominal plan quality and robustness. The purpose of this thesis is to develop methods that can facilitate decision making related to such tradeoffs. READ MORE

8. Implementation of MRI gel dosimetry in radiation therapy
Abstract : Gel dosimetry was used together with magnetic resonance imaging (MRI) to measure three-dimensional absorbed dose distributions in radiation therapy. Two different dosimeters were studied: ferrous- and monomer gel, based on the principles of radiation-induced oxidation and polymerisation, respectively. READ MORE

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

10. Development and application of composite energy deposition kernels for photon therapy planning
Abstract : 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. READ MORE
