This talk will review the evolution of radiation therapy over the last 20 years and discuss some of the newer advances in the field. Topics include a discussion of some of the more advanced planning techniques such as IMRT and VMAT as well as advances in imaging that make this possible. Additionally stereotactic radiotherapy and HDR brachytherapy techniques will be reviewed followed by a brief discussion of particle therapy.
