This is a study of two different setups when treating a patient with standard of care radiation doses. The study compares two patient setups (Standard Prone vs. Genital Drop Technique) with identical radiation treatment technique and parameters. After the two setups have been planned, the treating faculty reviews the setups and will choose the setup he feels that will give the patient improved dosimetry to the local regions and hopefully reduce toxicity and improve treatment tolerability.~Patients will not be randomized or stratified by demographic or disease risk assessment, but treatment will be tailored to stage specific current standards of care.~An extra (non standard of care) CT is required to analyze the data.
