Medical radiations


Medical radiations is a mix of technical expertise and patient care. It involves the use of ionising and non-ionising radiation for the diagnosis and treatment of injury and disease.

Medical radiations is a rapidly advancing healthcare discipline embracing the huge advancements in information technology, digital imaging and instrumentation, making it one of the most advanced and dynamic areas of clinical medicine today.


There are three main areas of specialisation within medical radiations: nuclear medicine, medical imaging, and radiation therapy.

Nuclear medicine (nuclear medicine technologist)

Nuclear medicine technologists are health care professionals who combine knowledge of biomedical and physical sciences with an understanding of patient care, in order to examine the physiology of organs and systems within the body.

Nuclear medicine uses very small amounts of radioactive materials to diagnose changes in the body and treat disease.

If you are interested in a career in the health sector, with direct patient care involving high-tech 3D medical imaging plus the preparation and dispensing of targeted drugs for imaging and treatment of disease, then consider enrolling in the nuclear medicine stream.

Graduates of nuclear medicine have extremely high employment rates both in Australia and overseas.

Medical imaging (radiographers)

Radiographers are health care professionals who assist in the diagnosis and management of patients, via the acquisition of medical images. These images of disease and injury are obtained using x-rays, Computed Tomography (CT) and Digital Subtraction Angiography (DSA). Magnetic Resonance Imaging (MRI) and Ultrasound (U/S) may also be used. Radiographers combine knowledge of the physical and biomedical sciences with technical expertise and patient care in their use of conventional and computer-assisted modalities.

Radiation therapy (radiation therapists)

Radiation therapists are health care professionals primarily concerned with the design and implementation of radiation treatment and issues of care and wellbeing for people diagnosed with cancer and other pathological conditions. Radiation Therapists also combine knowledge of the physical and biomedical sciences in order to design and verify appropriate treatment plans as well as in the delivery of treatment via the use of a variety of irradiation equipment. These professionals also conduct research into the treatment and prevention of cancer.

With each specialisation of the Medical Radiations programs you will spend 22 weeks in supervised clinical practice making you job-ready upon graduation.
