@Book{653803583, author="Kiesel, Antje", title="Approximated multileaf collimator field segmentation", year="2010", address="Rostock", abstract="In intensity-modulated radiation therapy the aim is to realize given intensity distributions as a superposition of differently shaped fields. Multileaf collimators are used for field shaping. This segmentation task leads to discrete optimization problems, that are considered in this dissertation. A variety of algorithms for exact and approximated segmentation, for different objective functions and various technical as well as dosimetric constraints are developed.", school="Universit{\"a}t Rostock", note="vorgelegt von Antje Kiesel", note="Dissertation Universit{\"a}t Rostock 2011", doi="10.18453/rosdok_id00000813", url="http://purl.uni-rostock.de/rosdok/id00000813", url="https://doi.org/10.18453/rosdok_id00000813", language="English" }
