IBCS seminar - ‘Spectral X-ray Tomography Imaging of Atherosclerotic Plaque’

Speaker: Professor Steven Gieseg from the University of Canterbury.

Event details



Prof Steven Gieseg is an Associate Professor in Biochemistry at the University of Canterbury’s School of Biological Sciences and holds an Honorary Associate Professor position in the Department of Radiology, University of Otago Christchurch. He leads the Free Radical Biochemistry Laboratory which specialises in the study of macrophage induced oxidative stress and the biochemistry of atherosclerotic plaques, with an emphasis on the biochemistry of the macrophage generated antioxidant 7,8-dihydroneopterin. Dr. Gieseg was a visiting Erskine Fellow at UEMS in 2011.

The need to understand the underlying structure of the plaque lead his team to join the MARS research collaboration in 2009 which is developing high resolution Spectral X-ray scanners using the MEDIPIX chip developed at CERN. He now leads the MARS Atheroma Imaging group developing spectral X-ray imaging of atheroma using both native X-ray absorbance and targeted contrast agents.

His seminar will cover what spectral X-ray imaging is and how it has the potential to completely change the way clinicians and scientist view the human body (and laboratory mice). Spectral-CT has the potential to deliver material identification similar to MRI but at magnified CT resolution, with scan times of only minutes.
