Legend: PTV = Planning Target Volume. CTV = Clinical Target Volume. VXXGy = Volume (%) receiving XX Gy. DXXcm3 = Highest dose to XX cm3 of the volume of interest. Figure S1 – Sagittal MR image displaying the bladder wall (BW) contours used for calculation of Doseacc. For reference, the Clinical Target Volume (CTV) and rectum contours are shown.
