High-Quality X-Ray Detectors for Low-Dose Imaging
X-ray-based imaging is the mainstay of medical imaging facilities around the world with over 20 million procedures annually in Canada. However, exposure to x rays also has a small risk - a risk that is accepted because immediate benefits of x-ray imaging outweigh the risks. We are studying the relationships between x-ray physics and detector design to learn how to ensure the next generation of x-ray systems will produce better images using less radiation. Engineering principles and methods developed by our group have formed the basis of “cascaded-systems theory” which is now widely used by engineers and scientists in the design and manufacture of modern x-ray systems.
