Carleton’s Science Café— X-Rays: From Röntgen to Digital Radiography and Beyond

X-rays are the key technology of hospital imaging departments, and are also used in dentistry, industry and for security scanning.  X-ray technology was the first to allow a doctor to look inside a patient without surgery.

When: Wednesday, Sept. 28, 2016 at 6:30 p.m.
Where: Sunnyside Branch of the Ottawa Public Library
The presentation will be followed by a question and answer session.

Today, hospitals have many other technologies, including ultrasound, MRI and nuclear medicine.  Yet X-ray technology, including the CT scanner, continues to be a major workhorse and continues to evolve to provide better and more convenient images with acceptable radiation doses.

In this talk, Paul Johns, professor of medical physics in the Department of Physics at Carleton University, will trace the development of X-ray technology starting with the inception of X-ray imaging at the close of the 19th century through to today’s computerized machines and on to the future, in which we will exploit the wave nature of X-rays, as well as their particle nature.  He will also look at where X-ray imaging is likely to go, and introduce some of the people behind the science.

The Science Café series is organized by the Faculty of Science at Carleton University to discuss relevant issues facing our society and how science can help solve real-world problems. Meet some of our award-winning faculty members and graduate students as they share their excitement about science with the community. For more information, visit: Sciencecafe.Carleton.ca.
