• 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.


LDI Alumni Profile


Dilendra Galhena

Master of Engineering Science (Research) graduate

Dept. Mechanical & Aerospace Engineering, Monash University Clayton Campus

Supervisors: Dr Josie Carberry & Professor Andreas Fouras


BEng(Mech, Hons) Monash 2009, MEngSc(Res) Monash 2014

Masters topic:

High precision microfluid control


The cell elasticity is known to be critical in blood cell function and is important in a number of disease states. Furthermore, Platelets are very sensitive to shear and their role in the formation of blood clots has been shown, using rudimentary methods to be shear dependent. The proposed project would assist to form a research tool to investigate, the role of shear in biological cells to cardiovascular diseases.
