The Applied Electromagnetics and Radiation Physics Research Group undertake a number of grant and industry funded projects in medicine and geophysics.
Image-guided synchrotron radiotherapy
A medical physics project to implement a method of image guidance for synchrotron radiotherapy trials on the imaging and medical beamline at The Australian Synchrotron.
Commissioning of a computerised treatment planning system for synchrotron radiotherapy trials
A medical physics project to test and validate the dose predictions from a computerised planning system against measured data obtained on the imaging and medical beamline at The Australian Synchrotron.
Project dates: 2016
Key people: Associate Professor Jeffrey Crosbie, Dr Daniele Pelliccia, Dr Jessica Lye, Dr Chris Poole
Grants and funding: NH&MRC Project Grant 2014-16

Development of an x-ray micro-CT system for biomedical microscopy
A biomedical imaging project to develop a dedicated x-ray microscopy for high resolution 3D biomedical microscopy.
A compact EM transmitter for use in boreholes and for portable surface applications
Most ground geophysical electromagnetic signal transmitters are cumbersome, and for maximising signal use large loops of wire laid out on the ground. These transmitters are unsuitable for operation in boreholes, and are not one-man-portable. This research is using advanced modelling software to design an optimum transmitter given weight and size constraints. Recent developments in nano-engineered magnetic cores are a major development that facilitates this project.

Using lightning location networks in natural field mineral exploration
Using precise knowledge of worldwide lightning strikes, we aim to compare measured and predicted amplitudes and directions of received electromagnetic transient signals. The amplitude attenuation with distance and directional changes predict geology, both under the survey site and backward along the path from the source lightning strike. New and inexpensive electromagnetic field sensors developed at RMIT are exceptionally sensitive to worldwide lightning, with 4 to 40 detected strikes per second, originating from different continents and hence different directions. Directional earth conductivity predictions will provide a novel tool for mineral explorers in their search for resources, and help predict geological structure at depth.
