Nonagenarian inventor welcomes challenges of noninvasive imaging

"It's the evolution of challenges that keeps one going. Many of my colleagues are quite satisfied with what they've done, and they're content to write histories about it. God bless them, but I think they're missing the day-to-day challenge of ongoing science. It's a continuum. If the problem is solved, the only good is that it's revealed another set of problems. I think that is the essence of creativity."

-Britton Chance, Ph.D., 93-year-old emeritus professor of biophysics, physical chemistry, and radiologic physics at the University of Pennsylvania and holder of more than 40 patents in the field of optical imaging for medical uses, in an interview with Diagnostic Imaging.
