OCT2013 – the first international symposium hosted by the Center for Biomedical OCT Research and Translation at Harvard Medical School and Massachusetts General Hospital, will focus on the latest and greatest technical capabilities of OCT, provide an overview of the commercially available OCT systems, discuss advancements in numerous clinical application areas, and introduce emerging preclinical optical imaging techniques. The unique emphasis of technology and clinical utility presented in the symposium will bring together an interdisciplinary group of expert clinicians, engineers, physicists, biologists, businesspersons, and trainees from around the world to foster the realization of OCT technology and implementation in the clinic ...
Swept source/Fourier domain OCT is demonstrated for in vivo imaging of the rodent eye. Using commercial swept laser technology, we developed a prototype OCT imaging system for small animal ocular imaging operating in the 1050 nm wavelength range at an axial scan rate of 100 kHz with ~6 µm axial resolution. The high imaging speed enables volumetric imaging with high axial scan densities, measuring high flow velocities in vessels, and repeated volumetric imaging over time. The 1050 nm wavelength light provides increased penetration into tissue compared to standard commercial OCT systems at 850 nm. The long imaging range enables ...
James. G. Fujimoto is a principal investigator in the Research Laboratory of Electronics (RLE) at the Massachusetts Institute of Technology (MIT). He received his S.B., S.M., and Ph.D. in electrical engineering from MIT in 1979, 1981, and 1984 respectively. He joined the MIT faculty in 1985 as Assistant Professor of Electrical Engineering. Since 1994, he has been Professor of Electrical Engineering at MIT and Adjunct Professor of Ophthalmology at Tufts University.
Professor Fujimoto's area of research involves the development and application of femtosecond laser technology, studies of ultrafast phenomena, and laser medicine and surgery. His research group in RLE and collaborators invented optical coherence tomography and pioneered its development.
James G Fujimoto has published over 250 journal articles, is editor or author of 5 books, and holds numerous U.S. patents for his discoveries. He is a fellow of the National Academy of Engineering and the American Association for the Advancement of Science. Among his many honors include the 1999 Discover Magazine Award for Technological Innovation and the 2001 Rank Prize in Optoelectronics.
Partnership between academics and industry was critical for the development of OCT and is a powerful approach for translating new scientific discoveries into real world clinical practice...Clinical researchers on our team as well as other clinicians at leading international medical centers worked with the early OCT technology, exploring new clinical applications and blazing a trail that the broader clinical community could follow. This interdisciplinary approach was key to the success of this technology.In MIT Researchers Dr. James Fujimoto and Mr. Eric Swanson Awarded the 2012 António Champalimaud Vision Award
OCT has the advantage that it can image 1 or 2 millimeters below the surface with high resolution, noninvasively...Increased imaging speed is important; it allows broader coverage or improved resolution...the concept is not that the technology is trying to diagnose the cancer per se, since excisional biopsies do that well...Instead, it is coupling 3D OCT scanning across the sampling area with standard biopsies.In Optical Tomography May Aid 3D Cancer Diagnostics
Ultrahigh-speed imaging is important because it enables the acquisition of large three-dimensional volumetric data sets with micron-scale resolution.In New High-speed 3-D Imaging System Holds Potential for Improved Cancer Screening
Excisional biopsy is one of the gold standards for the diagnosis of cancer, but is a sampling procedure. If the biopsy is taken in a normal region of tissue and misses the cancer, the biopsy result is negative although the patient still has cancer.In New High-speed 3-D Imaging System Holds Potential for Improved Cancer Screening
This device development is one of the major technical challenges in endoscopic OCT because probes must be small enough so that they can be introduced into the body, but still be able to scan an optical beam at high speeds...Increasing imaging speeds has also been an important research objective because high-resolution volumetric imaging requires very large amounts of data in order to cover appreciable regions of tissue, so rapid image acquisition rates are a powerful advantage.In New High-speed 3-D Imaging System Holds Potential for Improved Cancer Screening
These long wavelengths have improved image penetration in scattering tissues...In ophthalmology, there is research interest in using swept-source OCT at 1000 nm because it is less sensitive to cataracts and enables imaging in scattering tissues, such as the choroid, the vascular network behind the retina.In Ophthalmic Lasers Expand from Surgery to Detection and Diagnosis
OCT was developed in the early '90s, and it took more than 10 years before it became clinically accepted with the third-generation technology, the Zeiss Stratus.In Inventor speaks about history, development of OCT technology

Within the last few years optical coherence tomography has become a standard diagnostic for ophthalmology. New techniques are now enabling dramatic increases in image acquisition speeds. These advances promise to enable new and powerful three-dimensional visualization methods which could improve early diagnosis of disease and treatment monitoring.In MIT team takes high-res, 3-D images of eye
