  • Improving the accuracy of prostate radiation therapy treatments. Performed one of the first investigations in radiation oncology using digital imaging systems to measure the targeting of radiation beams to patient anatomy. Demonstrated that improved accuracy of positioning patients for treatment could be obtained with specific setup techniques.
  • One of the earliest works examining whether new imaging devices in radiation oncology could be used to measure and verify the accuracy of dose delivery to patients. Paper receives 15 citations per year. This led to a better understanding of using imaging systems to measure and verify patient dose in Radiation Oncology.
  • Development of a novel and improved method to calibrate imaging systems for use as dosimeters that retain beam profile information. The method has been further developed by a major commercial vendor and should be released for use for Radiation Oncology dosimetry.
  • Development of improved methods to ensure that radiotherapy treatment machines are operating accurately. Some of the methods are being commercialised by a radiotherapy software vendor (Standard Imaging) to be released in their PIPSpro software.
  • The first work to comprehensively examine a new method of ensuring that patient treatment is accurate in radiation therapy using time-resolved dosimetry. This can ensure that errors would be detected as soon as they occur which is not possible with current techniques. This was awarded 1st/40 applications by the American Society of Therapeutic Radiation Oncology (ASTRO) to improve patient safety for advanced modern treatment techniques such as IMRT.
  • Collaboration with a major linear accelerator vendor on a new imaging system to implement imaging-based dose verification. This system has improved dosimetric characteristics and improved methods to verify beam delivery. Currently working toward releasing a commercial product based on this work that would be utilised world-wide in radiation oncology centres.
  • Development of the first atlas-based deformable image registration method to map electron densities to MRI scans for dose calculations in collaboration with CSIRO. This could lead to the use of MRI scans directly for radiation oncology prostate planning without the need for further x-ray CT.
