Radiation oncology medical physicists are medical physicists who create, implement and monitor the procedures which allow the best treatment using radiation, taking into account the protection and safety of patients and others involved in the treatment process.Radiation oncology medical physicists are most typically involved with the safe operation and quality of systems used for imaging and treatment of patients. This can include machines such as linear accelerators, CT scanners, superficial X-ray machines, treatment computer systems and radioactive materials. Radiation oncology medical physicists are also responsible for implementing and ensuring the safety of new treatment techniques such as four dimensional (4D) CT imaging and image guided radiation therapy.Radiation oncology medical physicists work closely with IT and engineering staff to ensure all the radiotherapy equipment and computers are working correctly and linked together correctly.In their role, a radiation oncology medical physicist is consulted by radiation oncologists and radiation therapists to provide advice as to the best use of medical radiation for treatment and protection. Radiation oncology medical physicists make sure that all equipment meets international and national conditions so that the radiation dose recommended by the radiation oncologist and planned by the radiation therapist can be delivered to the patient correctly.
