Increasing treatment accuracy for cervical cancer patients using correlations between bladder-filling change and cervix-uterus displacements: Proof of principle

Pre-treatment acquired VBF-scans may be used to substantially enhance treatment precision of cervical cancer patients. Application in adaptive therapy is promising and warrants further investigation. For highly conformal (IMRT) treatments, the use of a full bladder drinking protocol results in unacceptably large systematic set-up errors.
