Table 2.
Dose volume histogram (DVH) metrics for the planning target volume (PTV), bladder and rectum for the nine subjects. For each subject, the top row represents the dose at the bladder empty state and the bottom row the dose at the bladder full state. Mean and standard deviation of the dose in the initial and final time points across all subjects has been calculated and the bottom row represents the significance of the difference between these doses in these two time points. Bold‐italized values indicate doses that are outside the accepted range
