"This work is dedicated to study the uncertainties occurring along the course of external\r\nbeam radiation therapy.\r\nAt first it was tested and assessed whether the quality of the detector systems used to\r\nanalyze uncertainties, as well as the rationale to decide if a plan is acceptable or not, is\r\nsufficient. The angular dependency was investigated for the selected detector system and a\r\ncompensation method is proposed. The capability of selected TPS to create reproducible\r\ntreatment plans in clinical conditions was examined as well by applying multiple definitions\r\nof complexity metrics.\r\nA major part of this thesis was dedicated to introduce two new complementary software\r\ntools to be used with TomoTherapy units. These tools allow users to identify the leading\r\ncauses for treatment failures using the built-in detector systems.\r\nFurthermore, we illustrate how these tools can be implemented in an adaptive radiotherapy\r\nframework by using their information to assess machine output and anatomical changes\r\ntogether with their dosimetry influence on the therapy outcome of a single fraction or\r\ncumulatively.\r\nSuch methodical studies of the occurring uncertainties and their implications contribute\r\nsubstantially to the quality of treatments in radio-oncology centers."^^ .
