   Sammanfattning : The aim of this thesis is to generate a starting guess for volumetric modulated arc therapy (VMAT) plan optimization by using data from an intensity modulated radiation therapy (IMRT) plan. We develop a mixed-binary linear programming model, based on choosing segments among a set of predefined segments. LÄS MER

   Sammanfattning : Introduction: Currently, patient specific dosimetric measurements on diode arrays such as Delta4® (ScandiDos AB) is a part of standard quality assurance (QA) for RapidArc® (RA) at Herlev University hospital. However, a standing issue is the interpretation of the results from dosimetric measurements into consequences in the delivered absorbed dose to the patient. LÄS MER
