Optical Coherence Tomography, OCT News
OCT for detecting decompression sickness
Dec 1, 2007 — Scuba divers, airplane pilots and people in submarines all can experience decompression sickness when their bodies are subjected to sudden, drastic changes in the surrounding air or water pressure. The condition can be fatal, but researchers led by...
Optical Coherence Tomography Aids Cancer Detection
Nov 1, 2007 — Optical coherence tomography (OCT) has been applied successfully in ophthalmology since the early 1990s, a success story triggering research efforts in the imaging of early epithelial cancers. Typical nonophthalmic systems achieve a resolution of 10...
Peering into the eyes to determine brain health
Nov 1, 2007 — Patients with multiple sclerosis often display decreased brain volume, a consequence of brain-cell breakdown brought on by the disease. MRI can detect the change, but it is costly and time-consuming. Researchers led by Dr. Peter Calabresi of Johns...
EURYI Winners Announced
STRASBOURG, France, Sept. 24, 2007 -- Researchers with big plans for molecular optoelectronic nanodevices, antimatter and biological nanomachines are among the 20 winners of the European Young Investigator (EURYI) awards for 2007. The awards are bestowed through scientific peer review...
OCT readers agree on retinal disease features in scans
Aug 1, 2007 — Optical coherence tomography (OCT) has become increasingly popular for evaluating and managing many retinal diseases, such as age-related macular degeneration (AMD). The OCT images of AMD obtained during conduct of clinical trials usually are...
Gloucestershire Royal Hospital
May 1, 2007 — Gloucestershire Royal Hospital of Cheltenham, UK, and University College London Hospital have agreed to use a medical imaging system from Michelson Diagnostics Ltd. of Orpington, UK, for research into rapid in vivo identification of cervical,...
High-Speed Laser System Takes Crisp, 3-D Retinal Images
CAMBRIDGE, Mass., May 1, 2007 -- In work that could improve diagnoses of many eye diseases, a new type of laser has been developed for taking high-resolution, 3-D images of the retina, the part of the eye that converts light to electrical signals that travel to the brain. The...
OCT and polarimetry hold promise for optical cancer screening
May 1, 2007 — Each year oral cancer kills about 10,000 people in the US alone. Another 20,000 are diagnosed with it. Of those who survive, many suffer painful surgeries to remove tumors and restore lost oral and facial tissue that otherwise would have left them...
Seeing large surface areas at the cellular level
Jan 1, 2007 — Researchers continually strive to develop techniques that can detect cancer and other abnormalities as early as possible. Seok H. Yun of the Wellman Center for Photomedicine, Harvard Medical School and Massachusetts General Hospital, all in Boston,...
Optical Technique Improves 'Virtual Biopsies'
BOSTON, Nov. 21, 2006 -- A new optical imaging technique, optical frequency-domain imaging (OFDI), can provide three-dimensional microscopic views of the inner surfaces of blood vessels and gastrointestinal organs and could be useful for identifying precancerous lesions and...
