Department of Medical Physics

Medical physics is a branch of physics incorporating the application of physics and engineering to medicine and health. Medical physicists work closely with medical doctors and are employed in universities, medical schools, hospitals and medical research institutes.
The main area that medical physicist involves are in the treatment of cancer by ionizing radiation (radiation oncology), ultrasound and nuclear magnetic resonance (diagnostic radiology), diagnostic imaging with radionuclides (nuclear medicine), diagnostic imaging with x rays, and in the study of radiation hazards and radiation protection (health physics).

Medical physicists are generally involved in four areas of activities: -

  • clinical service and consultation
  • research and development
  • teaching
  • administration

Medical Physics Unit, UMMC was operated in 2006 and currently located at on the Level 10 of Menara Selatan, UMMC. The unit involves the cooperation of science officers (physics) of UMMC and medical physics lecturers of University Malaya. This unit has been agreed by the UMMC Board of Management to be placed under the auspices of the UMMC Clinical Governance.
