1. 1. Robust optimization of radiation therapy accounting for geometric uncertainty

   Författare :Albin Fredriksson; Anders Forsgren; Timothy C. Y. Chan; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optimization; intensity-modulated proton therapy; uncertainty; robust planning; setup error; range error; intensity-modulated radiation therapy; multicriteria optimization;

   Sammanfattning : Geometric errors may compromise the quality of radiation therapy treatments. Optimization methods that account for errors can reduce their effects.The first paper of this thesis introduces minimax optimization to account for systematic range and setup errors in intensity-modulated proton therapy.

3. 2. High Performance Computing for the Optimization of Radiation Therapy Treatment Plans

   Författare :Felix Liu; Stefano Markidis; Artur Podobas; Albin Fredriksson; David Keyes; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; HPC; Radiation Therapy; Optimization; Numerical Linear Algebra; Interior Point Methods; Datalogi; Computer Science;

   Sammanfattning : Radiation therapy is a clinical field in which computer simulations play a crucial role. Before patients undergo radiation therapy, an individual treatment plan for each patient needs to be created based on the specifics of their case (a process often referred to as \emph{treatment planning}).
