Radiology Medical Physicists

Radiology Medical Physicists are the resident experts in the safe, effective and efficient application of radiation for medical diagnosis and treatment. They direct and advise on the use of x-ray apparatus, computered tomography (CT) and magnetic resonance imaging (MRI).

Radiology Medical Physicists are integral members of the multi-professional teams who deliver radiology services and play a particularly important role in the quality assurance of equipment and in ensuring optimum image quality. The development and implementation of the high standards required for effective mammography screening are an example of this. 

In procedures involving the application of ionising radiation, radiology medical physicists also play a crucial role in ensuring the quality of radiation doses. Their job is to calculate a dose of the minimum amount possible that is still capable of achieving diagnostic images of high quality.

For applications involving ionising radiation, medical physicists are crucial to ensuring that the dose administered to a patient contains the minimum amount of radiation possible to still achieve images of diagnostic quality.

Radiation Safety is the responsibility of medical physicists no matter their specialty. All other professionals rely on the medical physicist for radiation safety matters, advice and policy. 

Radiology Medical Physicists may be involved with physics applications associated with the following areas:
  • General X-ray (radiography) equipment, including dental units
  • Digital and computed radiography applications
  • Fluoroscopy
  • Mammography
  • Computed Tomography (CT)
  • Ultrasound
  • Magnetic Resonance Imaging (MRI)
Roles:
The tasks of a radiology medical physicist can include:
  • Patient and staff dosimetry
  • Dose estimates in the case of accidental exposure to ionising radiation
  • Foetal dose estimates and advice regarding exposure during pregnancy
  • Advice to pregnant staff members
  • Acceptance testing of equipment
  • Commissioning of equipment
  • Equipment quality assurance programs
  • Radiation safety
  • Shielding calculations and assessments
  • Compliance with radiation regulatory requirements
  • Tutoring of radiology registrars
  • Review of research applications involving exposure of volunteers to ionising radiation
  • Radiation safety courses / talks / training
