With 6 disease sites covered over a 3-day period, a broad range of experience and expertise is shared with the course attendees. The faculty is comprised of leading radiation oncologists and medical physicists from a variety of prominent institutions nationwide. The case-based course focuses on advanced practical applications taught through physician and physicist didactics and hands-on demonstrations. Disease sites covered are: CNS, H&N, Breast, Lung, GI and GU. The clinical school also covers advanced techniques such as SRS, SBRT, motion management, adaptive therapy and knowledge-based treatment planning, as well as clinical workflow development and advanced imaging implementation. Multiple quantities of this course may need to be purchased as each attendee requires a tuition. Attending as a multidisciplinary group is ideal for this course, as implementing new technology is most successful when all specialties are involved in the process. The intended audience is radiation oncologists and medical physicists. However, medical dosimetrists will also gain value from attending the course, but treatment planning is not explicitly covered. For comprehensive training in treatment planning please refer to EC103.
