Medical Physics is a branch of Applied Physics, pursued by medical physicists, 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.The roles of a medical physicist in diagnostic imaging include machine purchasing and installation, testing, quality control, and operation. Medical physicists in both radiation therapy and diagnostic imaging are often involved in research and teaching.Medical physicists also help to develop new technology for diagnosis and treatment, covering areas such as imaging techniques, radio therapies, electronics, and laser technology. Medical physics is a very fine career with very good job prospects.The job prospects for medical physicists are almost entirely found in radiation oncology, nuclear medicine and diagnostic radiology….
