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 ...

Methodist Hospital Research Institute receives a $301,316 NIH grant for Multi-Scale Optical Imaging of the Cancer Vasculature and Tumor Microenvironment. The principal investigator is Seok-Hyun (Andy) Yun. The program is part of a multi-year program that started in 2012 and ends in 2014. Below is a summary of the work. Core 2 will provide the five projects with a number of unique advanced optical systems; collaborate with the project investigators in the design, execution, and analysis of animal experiments; and develop new instrumentation and methodology as needs arise. The Core will be established in Boston within the Wellman Center ...

The ability to quantify and visualize submicrometer-scale oscillatory motions of objects in three dimensions has a wide range of application in acoustics, materials sciences, and medical imaging. Here we demonstrate that volumetric snapshots of rapid periodic motion can be captured using optical coherence tomography (OCT) with subnanometer-scale motion sensitivity and microsecond-scale temporal resolution. This technique, termed OCT vibrography, was applied to generate time-resolved volumetric vibrographs of a miniature drum driven acoustically at several kilohertz.

The Center for Biomedical OCT Research and Translation (CBORT), at Massachusetts General Hospital and Harvard Medical School is hosting its first annual OCT workshop, OCT: Technical Foundations and Systematic Implementation. The event will bring a highly select group of OCT engineers and researchers from academia and industry to Boston for intense theoretical and practical training of OCT principles and functionality. Lectures and hands on laboratory demos will be held by leaders in the field including: Professors Brett Bouma, Guillermo (Gary) Tearney, S.H. (Andy) Yun, and Ben Vakoc. Topics will include light source development, signal processing & system calibration, system integration ...

BELLINGHAM, Washington, USA -- New biomedical optics treatments for cancer and other diseases and for restoring sight, the latest green photonics enabling sustainable energy solutions, and laser innovations for manufacturing, communications, and much more are on the program at SPIE Photonics West next January in San Francisco, California. Photonics West -- already the world's largest international conference and exhibition on industrial and medical applications of optics, lasers, and photonics -- will be larger than ever in 2012, with more papers and expanded exhibition space. Dates are 21-26 January at the Moscone Center. More than 19,000 attendees are expected for technical sessions ...

Optical coherence tomography (OCT) can provide high-resolution ([sim]10-15 [mu]m/pixel) images of vocal fold microanatomy, as demonstrated previously. We explored physiologically triggered Fourier-domain OCT for imaging vocal folds during phonation. The goal is to visualize dynamic histological cross sections and four-dimensional data sets where multiple planes are displayed in synchronized motion. If feasible, this approach could be a useful research tool and spur development of new clinical instrumentation.A Fourier-domain, triggered OCT system was created and tested in experiments on excised calf larynges to obtain preliminary observations and characterize important factors affecting image quality.Larynges were imaged during ...

Multiple scattering in a sample presents a significant limitation to achieve meaningful structural information at deeper penetration depths in optical coherence tomography (OCT). Previous studies suggest that the spectral region around 1.7 μm may exhibit reduced scattering coefficients in ... [Opt. Express 16, 19712-19723 (2008)]
