Author: Kollotzek, S., et al, Universitätsklinik für Strahlentherapie-Radioonkologie, Medizinische Universität Innsbruck, Austria Summary: The goal of this project is to evaluate the accuracy of dose delivery for hybrid DCAT plans under different conditions, with a focus on how adjusting the linac’s maximum dose rate impacts the alignment between planned and delivered doses.
Author: R. Nachtigall, et al, Strahlenzentrum Hamburg MVZ, Germany Summary: The purpose of this project is to evaluate if the IQM is a reliable alternative to the phantom based patient plan verification offering the possibility to shift the QA to the first treatment fraction.
