Before Wilhelm Röntgen, a mechanical engineer, discovered a new type of electromagnetic radiation in 1895, physicians could only dream of being able to see inside the body. Within a year of Röntgen’s discovery, X-rays were being used to identify tumors. Within 10 years, hospitals were using X-rays to help diagnose and treat patients.
In 1972, computed tomography (CT) scans were developed. In the 1980s, magnetic resonance imaging (MRI) technology became commercially available.
Today, engineers like Thomas O’Sullivan, assistant professor of electrical engineering at the University of Notre Dame, continue the quest to improve the quality of medical diagnosis and treatment using near-infrared optical imaging.
O’Sullivan and his team are developing a powerful, pocket-sized optical imager that may once have seemed like the stuff of science fiction.
