Biographical details

Dr Paul Liu obtained his Bachelors degree from the University of Sydney in 2007 with majors in Physics and History and Philosophy of Science. He then completed his Masters in Medical Physics and undertook a PhD in the same field. During his doctorate, he worked in collaboration with the Chris O’Brien Lifehouse to develop new techniques to measure radiation therapy dose using fibre optics. These new methods improved the safety of brachytherapy treatments as well as those involving small radiation fields. In his spare time, Paul enjoys playing sport, travelling and photography.

Research interests

Radiation therapy is one of the main pillars of caner treatments. Treatment aims to kill cancer cells by delivering radiation to a localised target, while avoiding radiation dose to nearby healthy tissue. Radiation therapy is one of the most cost-effective cancer treatments and is recommended for approximately half of all patients worldwide. Dr Paul Liu is working on the Nano-X project that aims to improve global access to treatment and reduce the cancer burden worldwide. Nano-X is a new type of treatment system that utilises image guidance and patient rotation to offer high quality radiation therapy with a smaller, more robust and more cost-effective machine.

Current projects

The Nano-X radiotherapy system is a prototype treatment machine that utilises patient rotation and image guidance. Patient rotation is a concept designed to keep the radiation beam stationary, while still achieving the necessary beam angles to achieve a desired dose distribution. By rotating the patient instead of the heavy and complex linar accelerator, the treatment system can be made smaller, more reliable and less expensive to manufacture and maintain. Image guidance technologies will find the tumour and adapt treatment in real-time to ensure that radiation is delivered to the target. This will ensure that a high level of clincial accuracy for the system.
