  • 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.

2009 news

Summer Research Program begins

The 2009–10 Summer Research Program has commenced across Monash University. The Lab welcomes six students into the program this year, who will be conducting projects in the field of Biological Engineering in conjuction with supervisors Dr Kris Ryan and Dr Greg Sheard from the Department of Mechanical & Aerospace Engineering. We welcome Brendan, Joshua, Ilani, Xiang, Xiaojing and Zhaoyuan for the Summer. For more information on the projects that they will be conducting, please visit our Undergraduate page.

Installation of Quantronix femto-second laser completed

Installation of the Quantronix Odin-II multipass amplifier with integrated pump laser has been completed.

Successful experiments at SPring-8 synchrotron

Laboratory staff and students return home to Melbourne alongside collaborating researchers from the Department of Physiology, after completing a pleasing six days worth of experiments at the Japanese Synchrotron, SPring-8 — the third round of beamtime at SPring-8 for this year. All experimentation utilising the ventilator has been very promising.

Experiments in Fluids publication

Congratulations to Andreas Fouras, David Lo Jacono, Chuong Nguyen and Prof Kerry Hourigan for their paper entitled "Volumetric Correlation PIV: a New Technique for 3D Velocity Vector Field Measurement", published in Experiments in Fluids. Please see our 2009 Publications page for more details.

New high–speed camera

The Laboratory has purchased an IDT MotionPro Y6 high–speed camera to join its imaging family. The Y6 is capable of capturing 1504 x 1128 images at 1200 frames per second. This will allow experiments using biological system models to be conducted at physiological flow rates, at high sensitivity and good resolution. The camera will be taken on the upcoming trip to the Japanese synchrotron, SPring-8 next month.

Laboratory researchers attend PIV09 conference

Members of the Laboratory return back to the office after attending the 8th International Symposium on Partical Image Velocimetry, hosted at the Langham Hotel Melbourne between the 25th–28th of August 2009. Ten talks were presented detailing research conducted within our group; from X-ray PIV of airway motion to hydraulic analogy examination of shock cells to micro-PIV of velocity near the wall of a thrombus to optimisation techniques for PIV. For conference papers submitted by Lab members, please visit our 2009 Publications page.

COMET FeinFocus Cougar arrives

The Laboratory receives delivery of a COMET FeinFocus Cougar X-ray platform. The device features Computerised Numerical Control (CNC), allowing the operator to program and automate X-ray inspection procedures as well as perform precise 2D measurements without the need for calibration. The FeinFocus Cougar will provide an avenue of X-ray research to be conveniently conducted in the laboratory and will ensure that rigs bound for expensive synchrotron beamtime can be tested thoroughly prior. The X-ray platform will also be utilised to inspect structures of disease in biological systems.

Virtual Journal of Biological Physics Research publication

The invited review paper entitled The past, present, and future of x-ray technology for in vivo imaging of function and form, published in Journal of Applied Physics, has been selected for the June 1, 2009 issue of Virtual Journal of Biological Physics Research, which is published by the American Physical Society and the American Institute of Physics in cooperation with numerous other societies and publishers. It is an edited compilation of links to articles from participating publishers, covering a focused area of frontier research. Please see our 2009 Publications page for more details.

Researchers return from successful trip to synchrotron

Laboratory staff and students return home to Melbourne alongside collaborating researchers from the Monash School of Physics and Department of Physiology, after completing ten solid days of experiments at the Japanese Synchrotron, SPring-8 — the second round of beamtime at SPring-8 for this year. Initial analysis of results are very promising for both lung imaging and vascular PIV.

The Lab welcomes new PhD student Michael Curtis

The Laboratory group warmly welcomes Michael, our new PhD student. Michael comes to us from a Mechatronics Engineering background, and so his expertise will complement the skills and knowledge of the other postgraduate students in our laboratory group.

Nature Medicine thrombus growth collaborative paper

The Division of Biological Engineering's PhD student Elham, Dr Josie Carberry and Andreas, have collaboratively published a Nature Medicine paper on thrombus formation with Dr Warwick Nesbitt, Erik Westein and Prof Shaun Jackson from the ACBD at Melbourne's Alfred Hospital, and colleagues from RMIT University.

The paper entitled, "A shear gradient–dependent platelet aggregation mechanism drives thrombus formation", details how platelet aggregation at sites of vascular injury is essential for hemostasis and arterial thrombosis, driven from the past assumption that platelet aggregation and thrombus growth are initiated by soluble agonists generated at sites of vascular injury. The researchers used high-resolution intravital imaging techniques and hydrodynamic analyses to show that platelet aggregation is primarily driven by changes in blood flow parameters.

Collaborative paper publication in Journal of Synchrotron Radiation

Congratulations to Martin Donnelley, David Parsons, Andreas Fouras, and colleagues for their paper entitled "Real-time non-invasive detection of inhalable particulates delivered into live mouse airways" accepted for publication in Journal of Synchrotron Radiation. Please see our 2009 Publications page for more details.

The Lab welcomes new PhD student Jordan Thurgood

The Laboratory group warmly welcomes Jordan, our new PhD student. Jordan, who comes from a Mechanical Engineering background, will begin his PhD studies focusing on the development of lung ventilation techniques.

Preterm lung ventilation collaborative paper accepted to AJRCCM

Congratulations to Melissa Siew, Stuart Hooper, Andreas, and colleagues for their paper entitled "Positive end expiratory pressures are required to develop a functional residual capacity in preterm rabbits ventilated from birth" accepted for publication in American Journal of Respiratory and Critical Care Medicine. Please see our 2009 Publications page for more details.

Facelift for the wesbite

Our website has received a refreshing facelift to add clarity and navigational ease to the site. You will now notice that navigation has split into a top nav-bar in the header for basic links (as well as the inclusion of a new google search bar), and a left hand column menu which contains all other links. A breadcrumb trail directly under the header has also been added to all pages.
