Phase contrast tomography shows great promise in early stages of study and is expected to be tested on first patients by 2020.
An expert group of imaging scientists in Sydney and Melbourne are using the Imaging and Medical Beamline (IMBL) at the Australian Synchrotron as part of ongoing research on an innovative 3D imaging technique to improve the detection and diagnosis of breast cancer.
The technique, known as in-line phase-contrast computed tomography (PCT), has shown advantages over 2D mammography with conventional X-rays by producing superior quality images of dense breast tissue with similar or below radiation dose.
Research led by Prof Patrick Brennan of the University of Sydney and Dr Tim Gureyev at the University of Melbourne with funding from the NHMRC and the support of clinicians in Melbourne including breast surgeon Dr Jane Fox, is now focused on demonstrating the clinical usefulness of the technique.
Together with Associate Professor Sarah Lewis and Dr SeyedamirTavakoli Taba from the University of Sydney heading clinical implementation, the technique is expected to be tested on the first patients at the Australian Synchrotron by 2020.
