Research

Our research focus is x-ray imaging; over 400 million x-ray imaging procedures are performed each year in North America alone. We investigate novel x-ray imaging techniques and technologies with the goal of discovering those that will improve the quality of x-ray images and/or enable new, advanced x-ray imaging applications. We are currently investigating spectroscopic x-ray imaging of cardiovascular disease and breast cancer, in addition to dual-energy approaches for low-dose x-ray imaging of respiratory disease. Our research focuses primarily on understanding and quantifying relationships between the fundamental physics of x-ray imaging and the quality of x-ray images, with specific interest in the aforementioned applications. To this end, we develop and implement advanced theoretical and experimental methodologies for quantifying objectively the quality of medical x-ray images. We welcome trainees with strong backgrounds in physics and mathematics, as well as new collaborations in academia, hospitals and industry.
