“It makes use of infrared mild that’s barely seen in comparison with the intense flash of fundus pictures [another common method of eye imaging] and gives much more data—three-dimensional somewhat than two-dimensional data—at increased decision,” Huang says. The invention earned him and his co-inventors slots within the Nationwide Inventors Corridor of Fame in 2025 in addition to the Lasker Award and the Nationwide Medals of Know-how and Innovation in 2023.
Huang didn’t count on to vary the paradigm of eye imaging when he started learning electrical engineering as an undergraduate at MIT, however he was excited about utilizing an engineering mindset to contribute to medical developments. That, he thought, may very well be his strategy to comply with within the footsteps of his father, who was a household practitioner.
OCT emerged from his work as an MD-PhD pupil within the Harvard-MIT Program in Well being Sciences and Know-how. Whereas learning ultrafast lasers at MIT underneath James Fujimoto ’79, SM ’81, PhD ’84, the Elihu Thomson Professor of Electrical Engineering, Huang was tasked with utilizing the lasers to enhance varied ophthalmological duties, together with measuring the thickness of the cornea and retina.
Huang thought an strategy generally known as interferometry, which might measure the time of flight down to at least one quadrillionth of a second, might enhance thickness measurements to micrometer decision. Huang’s experiments revealed that the method was capable of detect very faint alerts arising from effective inside buildings throughout the retina. Fujimoto and Huang realized the potential for inventing a brand new kind of imaging and enlisted the assistance of Eric Swanson, SM ’84, who was utilizing interferometry for intersatellite communications at Lincoln Laboratory, to develop an OCT machine for organic purposes. Huang examined the brand new machine on a number of kinds of tissues accessed by means of Harvard Medical Faculty and located it notably profitable in imaging retinal and coronary artery samples. He and his colleagues printed their preliminary findings in Science in 1991, establishing OCT as a brand new imaging modality.
“Due to our means to kind collaborations with medical medical doctors and the extra superior applied sciences that had been simply accessible at Lincoln Lab and MIT, we had been capable of make this new imaging know-how take off when different individuals who had been exploring across the identical space weren’t capable of show imaging outcomes,” he says.
After the groundbreaking invention, Huang completed his tutorial and medical coaching as an ophthalmologist whereas Fujimoto and Swanson fashioned a startup firm to make sure that the system acquired into medical workplaces.
Over the following many years, Huang has continued to refine OCT for varied purposes. At present, because the director of analysis at Oregon Well being and Science College’s Casey Eye Institute, he leads analysis teams exploring new methods to make use of OCT in strategies equivalent to OCT angiography (imaging blood circulate all the way down to the capillary degree) and OCT optoretinography (mapping the sunshine response in retinal photoreceptor cells).
Along with conducting analysis, he additionally sees sufferers and is the cofounder of GoCheck Children, a digital platform for pediatric eye screening.
Huang credit his knack for innovation to his place on the nexus of various fields. “It’s laborious for a pure medical physician or a pure laser engineer to appreciate that there’s a possibility to invent a brand new system that solves an actual downside within the clinic,” he says. “However it’s very easy when you’ve gotten information on either side.”
