• Fun Facts

    Australians are exposed to 2 millisieverts of 'background' radiation per year
    A CT of the chest can be roughly equivalent to having 100 single chest X-rays
    15x Melbourne → Singapore → London flights exposes you to 1 millisievert
  • Diagnostic X-rays

    A diagnostic X-ray is the oldest and most common medical radiology procedure. Radiologists use X-rays to help diagnose disease or injury inside your body. A machine directs a small, carefully calculated amount of radiation toward a specific part of the body to produce an image on a film on the other side of the body. Radiologists study the X-ray images to detect and diagnose disease or injury.

  • CT dosage

    Computed Tomography (CT) is currently one of the major contributors to the collective population radiation dose due to the increasing popularity of CT examinations as a non-invasive diagnostic tool. The evolution of CT scanner technology has turned their use from specialized into routine examination. More due diligence is required due to the high radiation dose of CT.

  • Where to from here?

    It is of the utmost importance that both clinical justification as well as technical optimization are implemented to maintain a high benefit to risk ratio. Solid interdisciplinary partnerships and research endeavours between clinical specialists and technology engineers will help to fast track developments in this area.

Masters topic:

Advances in mechanical ventilation for the enhancement of preterm and premature infant respiratory assistance


An original new flow resistance system has been designed to increase the current level of functionality in modern ventilation systems. Through this, an innovative and unprecedented ventilation procedure has been designed and implemented. Additionally, new measurement devices have been designed and introduced, namely a novel flow sensor and a carbon dioxide sensor, and have profoundly increased the scope for data collection and analysis during mechanical ventilation. Similarly, the introduction of a more streamlined software interface has demonstrated a reduced ability to cause human errors and added programming resources has shown enhanced flexibility and research capability. Through the addition of revolutionary components and further developments, this work has expanded the possibilities of conventional mechanical ventilation research procedures to further reduce preterm infant morbidity and mortality.
