Follow Dr. McIntosh:

Chris McIntosh is a Scientist at the Techna Institute, the Peter Munk Cardiac Centre, and the Joint Department of Medical Imaging, at the University Health Network, an Assistant Professor in the Dept. of Medical Biophysics at the University of Toronto, and a Faculty Affiliate of the Vector Institute. Dr. McIntosh received the B.Sc. degree with honours in Computing Science from Simon Fraser University (SFU) in 2005 and his PhD in 2011 under the supervision of Dr. Ghassan Hamarneh. He is the recipient of academic awards from NSERC, CIHR, and the Michael Smith Foundation for Health Research. His dissertation received an honourable mention for the top dissertation in computer vision and medical image analysis by the Canadian Image Processing and Pattern Recognition Society. In 2010 he was a visiting researcher with the GALEN group at INRIA, Sacley, France, and Ecole Centrale de Paris. In 2012 he joined the Department of Radiation Physics as a Research Associate working in the labs of Drs. Tom Purdie and David Jaffray.

In 2019 he started his own lab focusing on the theory and clinical application of AI in medicine for improving patient care including transfer learning, meta learning, computer vision, and explainable AI. Applications include deep learning for automated diagnosis, segmentation, quality assurance, and treatment planning. In particular, his and Tom Purdie’s work in radiation therapy has been commercialized and is now deployed in hospitals around the world, using AI to deliver reproducible, high quality cancer care.

The focus of my lab is on advancing the theory and application of artificial intelligence (AI) in medicine from bench-to-bedside
  • Methodologies include transfer learning, meta learning, computer vision, and explainable AI to build clinically usable models
  • Close collaborations with clinical stake holders yield relevant clinical problems, and large data sets with tens of thousands of images
  • Developed technologies are used to prospectively provide patient care at UHN and globally
  • Diseases studied include prostate cancer, lung cancer, cardiovascular disease, and associated interventions
