Healthcare science staff in this area use their skills to develop methods of measuring what is happening in the body, devise new ways of diagnosing and treating disease, and ensure that equipment is functioning safely and effectively.

They support, develop and apply physical techniques such as ultrasound, radioactivity, radiation, magnetic resonance, electromagnetism and optical imaging to explore or record the workings of the body for diagnosis, monitoring and treatment.

Medical physicists will contribute to maintaining and improving the quality, safety and cost-effectiveness of healthcare services through patient-oriented activities requiring expert action, involvement or advice regarding the specification, selection, acceptance testing, commissioning, quality assurance/control and optimised clinical use of medical devices and regarding patient risks and protection from associated physical agents.
