Dr Kieran O'Brien is a Siemens Healthcare Adjunct Research Fellow at the Centre for Advanced Imaging. He completed his Bachelor of Biomedical Engineering (Honours, 2005) and PhD in Bioengineering from the University of Auckland in 2009. After being awarded his PhD Kieran worked in Postdoctoral positions at the University of Auckland and the University of Geneva Centre d'Imagerie BioMédicale before joining Siemens as a Senior Scientist in 2013.
Kieran has developed expertise as a sequence and image reconstruction software programmer for Siemens MR Scanners; developing, implementing and validating new advanced image acquisition and reconstruction techniques that overcome clinical and physical problems into commercial products. He has been responsible for leading the management of sequence projects to translate basic research from the lab on to Siemens scanners as software products that can be distributed worldwide. Of particular note is his involvement in the upgrade and development of the software for the new 7T Terra clinical system.
His research interests include improving RF pulses at high field (≥3T) to overcome imaging inhomogeneity and B1 limitations for Neuro, MSK and Cardiac applications; bi-exponential diffusion imaging; and, phase imaging for quantitative susceptibility mapping and measuring motion.
