    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.

Jordan Thurgood

PhD graduate


Dept. Mechanical & Aerospace Engineering, Monash University Clayton Campus

Supervisors: Professor Andreas Fouras, Professor Kerry Hourigan & Professor Stuart Hooper

Qualifications:

PhD Monash 2016 Graduate Certificate In Commercialising Research 2011
BEng(Mech, Hons) Monash 2009

PhD topic:

X-ray Imaging for Investigating Lung Function and Mechanics

Details:

Particle Image Velocimetry (PIV) is an advance flow field measurement technique capable of simultaneously taking many thousands of measurements over a flow field without disturbing the flow. Vast amounts of information can there for be gained form the application of such techniques to complex and sensitive flows.

Synchrotron based X-ray imaging has allowed for extremely detailed images of respiratory motions and lung structures to be visualized. Through the application of PIV techniques to synchrotron based X-Ray imaging of the lungs, this project seeks to develop a thorough understanding of complex respiratory phenomena such as HFOV and the hearts effect on the lungs.
