Medical Physicists are highly trained professionals work directly with the radiation oncologist to help determine the best radiation therapy technique for cancer treatment. The medical physicist oversees the planning process in conjunction with the Dosimetrist. It is the physicist’s responsibility to check the quality of radiation delivered by the equipment. They perform audits to assure the treatment is administered as prescribed by the physician. Medical physicists have a master’s degree or doctorate degree. They have completed four years of college, two to four years of graduate school, and typically one or two years of clinical physics training. They also are certified by the American Board of Radiology or by the American Board of Medical Physics in Radiation Oncology Physics.
