The aim of this study was to identify volume changes and dose variations of rectum and bladder during radiation therapy in prostate cancer patients. Therefore bladder and rectum were re-contoured on MVCTs once a week and the actual delivered radiation dose was calculated. For the rectum as well as the bladder, relevant interfraction variations of the organ volume and of the radiation dose could be observed. However, we could not identify a time trend during radiation therapy neither for the volumes nor for the doses.
