• 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.

Rajeev receives MST Outstanding Paper award

Dean Frieder Seible, Rajeev Samarage and Andreas Fouras

Congratulations to Rajeev, Andreas and co-authors who were awarded the MST Outstanding Paper award for the best paper published in MST during 2012 in the field of Fluid Mechanics, for their article, Polynomial element velocimetry (PEV): a technique for continuous in-plane velocity and velocity gradient measurements for low Reynolds number flows.

Dean of the Faculty of Engineering and the Faculty of Information Technology Frieder Seible presented the award to Rajeev Samarage and Associate Professor Andreas Fouras at Monash University. For more information please visit the MST announcements page.

The Editorial Board of MST writes, "The technique proposed in this article is highly relevant to the wide community of experimentalists that make use of particle image velocimetry. The authors have addressed the issue of how to accurately measure the velocity field and the velocity gradient distribution. The method proposed is elegant and innovative in that it introduces polynomial base functions to represent the spatially varying velocity field within an 'element'. The working principle is clearly described and illustrated. It is noted that the authors have taken a modest position by limiting their conclusions to the case of low Reynolds number flows. It is expected that further developments of this work could lead to successful applications at higher Reynolds numbers and turbulent flows. For the cases analyzed in this work, the authors have achieved a significant improvement in describing the velocity and the vorticity in proximity of the wall. Lastly, the authors have discussed with an open attitude the possible shortcomings of the method. They have indicated the points that will deserve attention when further research efforts are dedicated to the topic. Given the above considerations, the MST outstanding paper selection committee for measurements in fluids, chaired by Professor John Foss, has nominated this article for the MST 2012 outstanding paper award."

LDI finds a new home

new horizons
As the construction of the New Horizons building at the Monash University Clayton campus draws to a close, the Laboratory for Dynamic Imaging is pleased to announce its move from the Faculty of Engineering laboratories building into the custom design and specified labspace on Level 2 and 3 of New Horizons. This move sadly marks the end of an era for our group, but also the beginning of a very exciting and rewarding new phase of our group's current research endeavours. Our new research hub centres around a $2M Advanced X-ray Facility which contains a dedicated Control Room and Sample Preparation Room. We also have dedicated CAM and laser optics rooms, with access to a large open plan PC2 work area, specialist microscope, biological, and X-ray laboratories.

In memory of Stephen William Wilkins

It is with great sadness that the Laboratory for Dynamic Imaging pays tribute to Steve Wilkins, who passed in Melbourne on the 25th of March 2013. Steve's major contributions to the areas of X-ray methods and X-ray instrumentation paved the way for widespread implementation of hard X-ray phase-contrast imaging in research, as well as in industry and medicine, all areas of which our group's work belongs. It is by no exaggeration that Steve's pioneering work forms the solid ground from which our group's own hard X-ray phase-contrast imaging techniques are based.

Semester One begins

Semester One commences for 2013. We are glad to announce that LDI is once again running fourth year engineering elective, ENG4700 Biomedical Imaging & Sensing.

Summer Research Program draws to a close
