IMRT vs. 3-D XRT
External Beam Radiation using Photons
An alternative treatment for localized prostate cancer is external beam radiation therapy using photons. The treatment is performed by lying on a special table and directing an invisible beam to the proper area of the body. Both the amount and technique have changed considerably in the last ten years. This video explains 3-D conformal and Intensity Modulated (IMRT) methods, results and side effects.
