Mr Jarrad Begg

Back to

Jarrad Begg is an ACPSEM certified clinical medical physicist working at the Liverpool and Macarthur Cancer Therapy Centres. Whilst undertaking clinical training he obtained a MSc (Research) based on commissioning and quality assurance of an Optical CT scanner for 3D dosimetry. Jarrad’s professional interests include improving efficiency in quality assurance of equipment, dosimetry of ionising radiation, development of planning system software/scripts and educating students. Jarrad has started a PhD investigating the physical and dosimetric properties of a high field inline MRI-Linac on the Australian MR-Linac at the Ingham Institute for Applied Medical Research.
