Medical physics is the application of physics to medicine. It generally concerns physics as applied to medical imaging and radiotherapy, although a medical physicist may also work in many other areas of healthcare. A medical physics department may be based in either a hospital or a university and its work is likely to include research, technical development, and clinical healthcare. Of the large body of medical physicists in academia and clinics, roughly 85% practice or specialize in various forms of therapy, 10% in diagnostic imaging, and 5% in nuclear medicine. Areas of specialty in medical physics however are widely varied in scope and breadth.
