J. Quincy Brown (left), PhD, associate professor of biomedical engineering, and Brian Summa, PhD, associate professor of computer science, test a prototype of a revolutionary imaging system that will allow surgeons to scan a tumor site and determine within minutes whether any cancer tissue has been left behind, making repeated invasive surgeries unnecessary. Tulane University has been awarded up to $23 million from the Advanced Research Projects Agency for Health to lead a team of researchers in developing this technology over the next 5 years.
