Characterisation and improvement of radiation beams used for radiotherapy of small lesions. This project aims to characterise the radiation dose from a medical linear accelerator after the beam has been shaped by a mini-multileaf collimator. The characterisation will be achieved through a combination of computer simulations and experimental investigation of the beam using the technique of three-dimensional gel dosimetry. When the dosage characteristics are known, techniques will be developed to ....Characterisation and improvement of radiation beams used for radiotherapy of small lesions. This project aims to characterise the radiation dose from a medical linear accelerator after the beam has been shaped by a mini-multileaf collimator. The characterisation will be achieved through a combination of computer simulations and experimental investigation of the beam using the technique of three-dimensional gel dosimetry. When the dosage characteristics are known, techniques will be developed to improve radiotherapy treatments in patients with small lesions with sizes of up to a few centimetres. This will lead to an improved outcome for some cancer patients.Read moreRead less
Rare isotopes as tracers of prosthesis debris. The incidence of knee replacement surgery in Australia is 30,000 per year. Limited by wear debris, the lifespan of knee implants is only 10-15 years and can be much shorter. Due to increasing life expectancy, many patients need several surgical procedures. As a multi-disciplinary team of materials-, isotope-tracing- and medical-experts, we aim to understand and monitor wear debris in prostheses. Knee replacement surgery alone imposes a high burden o ....Rare isotopes as tracers of prosthesis debris. The incidence of knee replacement surgery in Australia is 30,000 per year. Limited by wear debris, the lifespan of knee implants is only 10-15 years and can be much shorter. Due to increasing life expectancy, many patients need several surgical procedures. As a multi-disciplinary team of materials-, isotope-tracing- and medical-experts, we aim to understand and monitor wear debris in prostheses. Knee replacement surgery alone imposes a high burden of annually half a billion dollars on the Australian health budget. Controlling and reducing wear debris in prosthesis joints would reduce these costs and improve patients' quality of life.Read moreRead less
