Radiopaque Hydrogel Rectal Spacer for Prostate Cancer Radiation Image Guidance
Objective
The purpose of the study is to determine if a radiopaque hydrogel rectal spacer, SpaceOAR Vue?, can be used in place of fiducial markers when aligning patients for radiotherapy. We hypothesize that the alignment of the patient based on the rectal spacer will be similar to the alignment of the patient with fiducial markers.
