Patients with localized prostate cancer are routinely treated with radiation therapy to the entire prostate gland. The investigators can identify where the cancer is concentrated in the prostate gland using a newer specialized imaging technique called 11C Choline PET (stands for choline positron emission tomography). This is different from the older type of PET scan that has been used in the past (called FDG PET) which has not been as accurate as the new PET scan for identifying where the cancer is in the prostate gland. It has also been shown that delivering higher doses of radiation to prostate cancer cells in the prostate have resulted in better cure rates in patients with prostate cancer. Therefore for goal number one the investigators want to give higher radiation dose to the prostate cancer cells. But the challenge has been that delivering higher doses of radiation to the prostate gland may also increase the chance of complications from the higher doses of radiation to the rectum, bladder and surrounding area. Therefore for goal number two the investigators want to minimize radiation dose to the rectum, bladder and surrounding area. 3-Tesla Magnetic Resonance Imaging (3T MRI) is a new kink of scan that will be used in this study to identify the urethra in the prostate so that the investigators can minimize the radiation dose to the urethra. The investigators believe the 3T MRI scan is able to point to the areas of cancer that may be able to predict how well the treatments may work, as well as which areas of the tumor appear to be responding to failing. In this study, the investigators will keep the dose of radiation to the rectum and bladder as low as possible while increasing radiation dose to parts of the prostate with more cancer cells. The investigators will compare the cure rates in this study with the cure rates of other patients receiving the standard treatment in which the same dose of radiation is delivered throughout the prostate gland. The investigators will also compare the rates of complications in this study with the rates of complications in patients receiving the standard treatment in which the same dose of radiation is delivered throughout the prostate gland.
