Medical physics deals with the application of the concepts and methods of physics to the prevention, diagnosis and treatment of human diseases with a specific goal of improving human health and well-being. Since 2008, medical physics has been included as a health profession according to International Standard Classification of Occupation of the International Labour Organization.
A radiation therapist, therapeutic radiographer or radiotherapist is an allied health professional who works in the field of radiation oncology. Radiation therapists plan and administer radiation treatments to cancer patients in most Western countries including the United Kingdom, Australia, most European countries, and Canada, where the minimum education requirement is often a baccalaureate degree or postgraduate degrees in radiation therapy. Radiation therapists can also prescribe medications and radiation, interpret tests results, perform follow ups, reviews, and provide consultations to cancer patients in the United Kingdom and Ontario, Canada . In the United States, radiation therapists have a lower educational requirement and often require postgraduate education and certification in order to plan treatments.
The Temerty Faculty of Medicine is the medical school of the University of Toronto. Founded in 1843, the faculty is based in Downtown Toronto and is one of Canada's oldest institutions of medical studies, being known for the discovery of insulin, stem cells and the site of the first single and double lung transplants in the world.
The Princess Margaret Cancer Centre is a scientific research centre and a teaching hospital in Toronto, Ontario, Canada, affiliated with the University of Toronto Faculty of Medicine as part of the University Health Network. The hospital now stands as the largest cancer centre in Canada and one of the five largest cancer centres in the world. Along with the Odette Cancer Centre, which is also associated with University of Toronto Faculty of Medicine and is independently the sixth largest cancer centre in North America, it forms one of the largest cluster of cancer hospitals in the world.
Harold Elford Johns was a Canadian medical physicist, noted for his extensive contributions to the use of ionizing radiation to treat cancer.
A medical physicist is a health professional with specialist education and training in the concepts and techniques of applying physics in medicine and competent to practice independently in one or more of the subfields (specialties) of medical physics. A medical physicist plays a fundamental role in applying physics to medicine, but particularly in the diagnosis and treatment of cancer. The scientific and technological progress in medical physics has led to a variety of skills that must be integrated into the role of a medical physicist in order for them to perform their job. The "medical services" provided to patients undergoing diagnostic and therapeutic treatments must, therefore, be the result of different but complementary skills. In general, the medical physicist is responsible for all scientific and technical aspects of imaging, radiation treatment, and radiation safety. It is their occupational role to ensure that medical modalities offered to patients are met with the utmost quality assurance. It is the medical physicist that manage and supervise the efforts of dosimetrists, therapists and technologists in that capacity.
Robert A. Phillips is a Canadian scientist, with a long-term interest in cancer research, and special interests in blood cell development and in retinoblastoma, an inherited eye tumour in children. His expertise has spanned the breadth of disciplines including radiation biology, cellular and molecular biology, immunology and molecular genetics.

Helen Sarah Freedhoff was a Canadian theoretical physicist who studied the interaction of light with atoms. She gained her doctorate at the University of Toronto in 1965 and completed a postdoctoral fellowship at Imperial College in London. Freedhoff was the first woman appointed as a physics professor at York University in Toronto, and is believed to have been the only woman professor of theoretical physics in Canada at the time.
Jeffrey Harold Siewerdsen is an American physicist and biomedical engineer who is a Professor of Biomedical Engineering, Computer Science, Radiology, and Neurosurgery at Johns Hopkins University. He is Co-Director of the Carnegie Center for Surgical Innovation at Johns Hopkins School of Medicine and is a member of the Malone Center for Engineering in Healthcare. He is among the original inventors of cone-beam CT-guided radiotherapy as well as weight-bearing cone-beam CT for musculoskeletal radiology and orthopedic surgery. His work also includes the early development of flat-panel detectors on mobile C-arms for intraoperative cone-beam CT in image-guided surgery. He developed early models for the signal and noise performance of flat-panel detectors and later extended such analysis to dual-energy imaging and 3D imaging performance in cone-beam CT. His core laboratory at Johns Hopkins University is the ISTAR Lab in the Department of Biomedical Engineering at the Johns Hopkins Hospital.
