Abstract
Over 400 million x-ray imaging examinations are performed each year in North America. The contrast of a material, for example a cancerous nodule or a contrast-enhanced coronary artery, in an x-ray image is dependent upon the energy of the x-rays used to produce the image, the atomic number of the material and the density of the material. Importantly, the energy-dependence of image contrast is material-dependent. Acquiring multiple x-ray images at different x-ray energies therefore enables enhancing or suppressing the contrast of different tissues with the goal of improving disease detectability or visualization. In this talk, Dr. Tanguay will present his lab’s recent work on novel approaches to, and applications of, multi-energy x-ray imaging of cardiovascular disease, functional lung imaging, and computed tomography, with particular focus on photon-counting x-ray detectors, which are poised to play a substantial role in the next generation of medical x-ray imaging.
Bio
Dr. Tanguay is an Assistant Professor at Ryerson University. Prior to joining Ryerson, he was an Assistant Professor at UBC’s Okanagan Campus, a Postdoctoral Fellow at UBC-Vancouver, and a PhD student in the Medical Imaging Labs at Robarts at Western University. Dr. Tanguay’s research focuses on modelling x-ray image quality with the goal of identifying novel x-ray imaging techniques and technologies that will improve disease visualization.
