Gregory Bootsma, PhD
Gregory Bootsma graduated from the University of Waterloo with a B.A.Sc. and M.A.Sc. from the Department of Engineering, where he focused on algorithm design, computer vision, and 3D reconstruction. Upon graduation Gregory joined the Image Guided Therapeutics (IGTx) lab working with Dr. David Jaffray and Dr. Jeff Siewerdsen developing both hardware and software for radiation and surgical guidance systems. Gregory went on to do a Ph.D. in the Department of Medical Biophysics at the University of Toronto under the supervision of Dr. Jaffray. The focus of his thesis was reducing scatter in Cone-beam CT through the use of physics and computational methods to improve image quality. Gregory continues to work to improve X-ray imaging using Monte Carlo techniques to model and generate new X-ray source design, improve image quality, and facilitate overall imaging system design.
