Washington, Aug 2 (ANI): A new imaging system that enables high-speed, three-dimensional (3-D) imaging of microscopic pre-cancerous changes in the esophagus or colon has been developed by researchers at the Massachusetts Institute of Technology.
The new system is based on an emerging technology called optical coherence tomography (OCT), which offers a way to see below the surface with 3-D, microscopic detail in ways that traditional screening methods can?t.
The new imaging system reported by OCT pioneer James G. Fujimoto of MIT and his colleagues, works at record speeds, capturing data at a rate of 980 frames per second-nearly 10 times faster than previous devices-while imaging microscopic features less than 8 millionths of a meter in size.
At such high speeds and super-fine resolution, the novel system promises to enable 3-D microscopic imaging of pre-cancerous changes in the esophagus or colon and the guidance of endoscopic therapies.
"Ultrahigh-speed imaging is important because it enables the acquisition of large three-dimensional volumetric data sets with micron-scale resolution," says Fujimoto, a professor of electrical engineering and computer science and senior author of the study.
The new device has been described in the Optical Society?s (OSA) open access journal Biomedical Optics Express. (ANI)
