Principal investigator

Image processing group

  • Perry Radau received his B.Sc. in astrophysics from the University of Calgary, followed by an M.Sc. in neuroscience and a PhD in medical biophysics from the University of Western Ontario. His PhD studies focused on the development of automated analysis techniques for brain receptor and perfusion images. He was employed by Hermes Medical Solutions to develop the FDA-approved, clinical software BRASS for analysis of brain images. Perry was then recruited by Sunnybrook to develop a visualization platform and other technical resources for the Ontario Consortium of Cardiac Imaging. In 2007, he led the technical office of the Imaging Research Centre for Cardiac Intervention (IRCCI) that is developing software for visualization of real-time MRI and fluoroscopy fused with prior 4-D images (MR, CT).
  • Yingli Lu received his B.A.Sc. and M.A.Sc. in applied mathematics from HeBei University of Technology in 1998 and 2001, followed by a PhD in pattern recognition and intelligent control from Chinese Academy of Science in 2004. His current projects at Sunnybrook include developing imaging, segmentation, registration and visualization software and models for real-time MR-image guided cardiac interventions.

Research engineer/Physicist

  • Bonny Biswas received her B.Sc. in computer science and biochemistry from Queen's University in 1996. After working at medical software companies, she began collaborating with Dr. Wright's group while at the Hospital for Sick Children. She joined the Wright group in 2007 and her current work involves software development for the OCCI viewer and the real-time MRI platform.

Research physiologist

  • Xiuling Qi received her PhD from the department of physiology in the faculty of medicine of the University of Montreal in December of 1997. Her current work involves studying noninvasive evaluation of blood volume in tissue that is useful in various clinical studies, including assessment and therapy monitoring in tumours.

Research associates

  • Venkat Swaminathan received his masters in biomedical engineering in 2001 and worked for GE Medical Systems. He joined the Wright group in December 2005 and has been working on new pulse sequences for MR-real-time and t2prep, tools for data-analysis and efficient waveform design.
  • Yuesong Yang received his MD and PhD in medical imaging from the Shanghai Medical University in 1993. His current research interests include the in vivo evaluation of oxygen-sensitive MR imaging in animal models and the correspondent translational clinical research.
  • Dingrong Yi received her BAEng in interface technology and B.A.Sc. in nuclear physics from the National University of Defense Technology in China in 1990. She received her first M.A.Sc. in solid state physics from Tsinghua University in China in 1996 and her second M.A.Sc. in atmospheric physics from McGill University in Canada in 1998. She then received her PhD in electrical and computer engineering from McGill University in 2002. Her research interests focus on interactive imaging and image-guided interventions. She is currently working on the design and development of the plane navigator and associated graphical user interface for the efficient and intuitive scan plane control of an MRI scanner.
