W I N T E R / S P R I N G U O F L M A G A Z I N E | 2 7 E N V I S I O N I N G T H E F U T U R E guidance has produced impressive results, including 31 students who have earned their master's degrees and 21 PhDs who themselves have gone on to distinguished careers. The lab's work has received five patents, appeared in hundreds of peer-reviewed articles, and featured in scientific venues around the world, including Australia, Singapore, Japan, China, Egypt, Turkey, Brazil and throughout Western Europe as well as the U.S. For his contributions to image modeling and biomedical applications, Dr. Farag was recently named a Fellow of the Institute of Electrical and Electronics Engineers (IEEE), among the most prestigious honors bestowed on electrical engineers worldwide. He has also chaired leading conferences in the field of imaging and has served as associate editor of technical publications. For all the accolades and recognition, Farag is quick to praise the students and their accomplishments. "These guys are the superstars, they're doing incredible work." IMPRESSIVE BODY OF EVIDENCE Some of the most developed technologies in the lab involve biomedical imaging to provide medical professionals with an unprecedented visualization of anatomy to enhance diagnosis and treatment. U.S. patents have been issued for Farag's work on developing software programs that can read CT scans of a lung or colon and identify potentially cancerous growths, even when they are small or hidden and may escape notice using traditional methods. "Lung and colorectal cancer are among the leading causes of cancer deaths in the U.S., but they don't have to be," notes Farag. "Early detection and diagnosis mean early treatment, and that improves the prognosis significantly." For colon cases, the imaging software uses a traditional CT scan to construct a 3-D version of the colon. By visualizing it in this way, Farag's team replicates what a doctor would do in an actual colonoscopy, but it is done virtually. "You reconstruct the colon and then you visualize it from all different viewpoints. But what we did, which was different, we took it a step further. We took the 3-D colon and cut it into two halves and it becomes like two rivers or ravines. And then we have a camera that does a 'virtual fly-over' and reads each half. We've been able to demonstrate that this approach sees more, and like everything else, when you see more, you diagnose more." In fact, Farag states that this approach improves accuracy by 10% compared to competing visualization approaches. "And that's extremely important because now we are able to see polyps that are smaller in size and might be hidden in the many folds that are prevalent in the colon." Facial thermal images can be used to determine vital signs by highlighting areas of the forehead and around the eyes that are rich with blood vessels, while video imaging enables analysis of different expressions. Com- bined, thermal and video imaging can provide insights into a person's state of mind.

"The applications touch multiple fi elds from law enforcement and security, to health care, engineering, education, computer science…it's amazing to think about the things we may be able to do with this technology." —Aly Farag U L _ 2 7 2 7 UL_27 27 1 / 2 7 / 1 4 9 : 3 8 A M 1/27/14 9:38 AM
