Decreasing the Dose to the Rectal Wall by Using a Rectal Retractor during Radiotherapy of Prostate Cancer: A Comparative Treatment Planning Study
Figure 3
DVH of the bladder for one representative patient, where the solid line is with retractor and the dashed line is without the retractor. In the left DVH, the bladder volume is presented as relative volume (%) and in the right DVH the bladder volume is presented as absolute volume. Note that the rectal retractor does not influence the dose to the bladder volume.
