Medical Physics Unit

Medical physics is concerned with the application of physics to medicine, particularly in the diagnosis and treatment of disease.

The Medical Physics Unit, established in 1979, is counted as one of the strengths of the Radiation Oncology Program. The collaboration of medical physicists and physicians has resulted in the development of a number of highly innovative treatment techniques and has contributed significantly in the area of technology assessment and development.

The Unit’s main areas of interest include:

  • The treatment of cancer by ionizing radiation (radiation oncology);
  • Diagnostic imaging with x rays, ultrasound and nuclear magnetic resonance (diagnostic radiology);
  • Diagnostic imaging with radionuclides (nuclear medicine);
  • The study of radiation hazards and radiation protection (health physics).

Other applications of physics to medicine include:

  • Bioelectrical investigations of the brain and heart (electroencephalography and electrocardiography);
  • Biomagnetic investigations of the brain (magnetic source scanning);
  • Medical uses of infrared irradiation (thermography), heat for cancer treatment (hyperthermia), and lasers for surgery (laser surgery).

The Medical Physics Unit offers training leading to the M.Sc. and Ph.D. degrees, as well as a two-year residency training program. The medical physics residency program is the only accredited program in Canada and one of only 10 in North America.
