Purpose:To assess the benefit of using bladder wall sub-volume equivalent uniform dose(EUD) constraints in prostate cancer IMRT planning.Methods and Materials:Two IMRT plans,with and without EUD constraints on the bladder wall,were generated and compared for 53 prostate cancer patients,to deliver 80Gy to the prostate PTV.The bladder wall was defined by the volume between the external manually delineated wall and a contraction of 7 mm from this external wall.
