The Department of Radiation Oncology at Washington University School of Medicine has a long history of innovation and development.

Over the years, we have been among the leaders in the clinical implementation of major technical breakthroughs in Radiation Oncology. This has extended from the early days of high energy linear accelerators and the first desktop treatment planning computers, through 3-dimensional treatment planning and intensity-modulated radiotherapy, proton therapy and image guided therapy today. Researchers in the Cancer Biology Division have been at the forefront in elucidating the mechanisms of radiation response, including the effects of hyperthermia (heat treatment) on radiation sensitivity.  In recent years we have also developed a series of collaborative research projects with our colleagues in diagnostic radiology, building on new opportunities to image important biologic functions.
