Medical physics

Medical physics research at the University of Adelaide focuses on improving healthcare through enhanced clinical radiotherapy and medical imaging, and future clinical applications of proton therapy.

Cancer trreament

Our research occurs in collaboration with the expertise and specialised training of affiliate medical physicists at several Adelaide hospitals.

Our experts work at the forefront of healthcare, in cancer treatment facilities, diagnostic imaging departments and hospital-based research establishments - often involving the use of x-rays, ultrasound, magnetic and electric fields, infra-red and ultraviolet light, heat and lasers in diagnosis and therapy.

We also have a variety of medical and health based research projects which utilise the application of optics, photonics and lasers and environmental luminescence techniques.

  • Radiobiological modelling

    Many physical principles are applicable in the analysis of tumour development and retardation with therapy.

    This program is applying Monte Carlo techniques to model the growth of a tumour from a single cell.

    Similar techniques are then being applied to examine the response of the tumour to radio and chemotherapy. Experimental work is also being conducted in conjunction with the IMVS to substantiate the developed models.

  • Solid state dosimetry

    Radiotherapy is currently based on a predictive methodology: external beam and brachytherapy source parameters are measured and modelled by the planning computer to predict the dose distribution within the patient.

    However, as all physicists know, there are experimental uncertainties. Therefore, the dose delivered to the patient may not be as precise as the theory predicts. Affiliate research staff with expertise in solid state dosimeters and optical dosimetry systems in particular are developing a range of novel dosimeters for applications in radiation oncology.

  • Proton therapy

    proton-therapy

    Proton therapy is a rapidly expanding field in radiation oncology and in 2017 the Australian Federal Government and South Australian State Government committed over $100 million to establish Australia's first proton therapy centre in Adelaide. Protons have a more favourable dose deposition characteristic than X-rays when it comes to treating deep-seated tumours and may reduce treatment related toxicities for certain patients.

    Our research group is working on a number of aspects of proton therapy including radiobiological modelling comparisons between protons and x-rays and novel image guidance techniques to allow for online adaptive radiotherapy.
