What is Medical Physics?

According to the International Organization of Medical Physicists, Medical Physics is a branch of applied physics that uses physics principles, methods and techniques in practice and research for the prevention, diagnosis and treatment of human diseases with a specific goal of improving human health and well-being.n

Within the field of Medical Physics, one can peruse a sub-specialty which includes Radiation Oncology Physics, Diagnostic Radiology Physics, Nuclear Medicine Physics and Health Physics.

Radiation Oncology Physics

Physicist who choose this specialty are usually based in Hospitals or Radiation Oncology Centers with an active role in External Beam Radiotherapy, Brachytherapy, Therapeutic I-131 treatment, quality assurance and radiation protection.

Diagnostic Radiology Physics

This career path usually places physicists in the Radiology Department of a Hospital where both ionizing and non-ionizing radiation is used. Diagnostic Physics play an active role with quality assurance, optimizing of imaging modalities and radiation protection.

Nuclear Medicine Physics

Nuclear Medicine Physicists are based within a nuclear medicine department and actively involved with quality assurance, optimization and radiation protection.

Health Physics

Based in both medical and industrial settings whereby ionizing radiation is used. Involved heavily with radiation protection and promotion of correct radiation protection measures, emergency/response planning, dosimetry and radioactive waste management.

Research and Teaching

Apart from clinical/industrial work, research and teaching are vital in the development of a medical physicist. They are actively involved with cancer research, improving or creating new treatment techniques, imaging modalities and radiobiology etc.
