Correlating scored daily anatomical changes to in-vivo EPID dosimetry and cone beam CT based dose calculations: A retrospective study

At the Antoni van Leeuwenhoek Hospital/Dutch Cancer Institute (NKI-AvL) in Amsterdam, inter-fractional anatomical changes during the course of radiotherapy are monitored using cone beam CT scans, taken prior to irradiation. These scans are assessed visually, and the fractions are scored according to a 'traffic light protocol'. Based on the...
