[]Primary outcomes (1)
- measure
- The percentage of patients who are able to achieve a bladder volume within +/- 30% of planning volume, on all treatment CBCT (cone beam computed tomography) scans
Secondary outcomes (3)
- measure
- The per-patient standard deviation of bladder volume throughout the course of radiotherapy
- measure
- The percentage of patients who are unable to follow the bladder filling protocol at any point during their treatment.
- measure
- The correlation between bladder volume and small bowel volume planning target volume
