This course explores the principles and practices of modern radiotherapy procedures. Students are introduced to the main equipment utilized in external beam radiation therapy and the fundamentals of treatment using photon and electron beams. Radiotherapy is one of the major treatment options in cancer management. In accordance with modern data and practices, 50% of patients should receive radiotherapy at least once during the treatment of their cancer. Together with surgery and chemotherapy radiotherapy plays an important role in the treatment of 40% of
those patients who are cured of their cancer. Radiotherapy is also a highly effective treatment option for palliation and symptom control in cases of advanced or recurrent cancer. This is a core course for the qualification of clinical medical physicists.
