Conjoint A/Prof. Peter Greer

Biography

A/Prof Greer is a clinically trained medical physicist who has been in a full-time research position since 2008. He leads the medical physics research group based within Radiation Oncology at the Calvary Mater Newcastle Hospital. He graduated with a PhD in medical physics in 2001 and was accredited in radiation oncology medical physics in 2003. A/ProfGreer's major interest is in patient dose verification in radiation oncology, specialising in flat-panel imaging devices. Currently he is collaborating with several leading overseas research groups as well as manufacturers to implement his work commercially.

He also has a longstanding interest in image guided radiation therapy and is a member of the IGRT expert group for the Trans-Tasman Radiation Oncology Group (TROG). More recently, in collaboration with CSIRO he has been investigating novel and adaptive methods to improve treatments in radiation therapy. His work in MRI based planning won an international challenge in automatic prostate segmentation in MRI images (MICCAI, London, 2009). He assists wherever possible with clinical trial analysis and quality assurance for the Prostate Clinical Trials Group (PCTG).

Collaboration

• Patient dose verification with flat-panel imaging devices

These are patient imaging devices used to align radiation beams to the tumour. To also utilise these to measure and verify that the patients receive accurate dose delivery.

• MRI-based therapy planning

The use of MRI images for radiotherapy planning including deformable image registration based automatic organ segmentation and the mapping of electron density to the MR scans for dose calculation. Collaboration with the MRI-linac project in Sydney.

• Image-guided radiation therapy and adaptive treatment strategies

Investigating novel and adaptive methods for delivering treatments in radiation therapy using cone-beam computed tomography acquired at each treatment session.
