Simultaneous dual-band optical coherence tomography for endoscopic applications.
Dual-band optical coherence tomography (OCT) can greatly enhance the imaging contrast with potential applications in functional (spectroscopic) analysis. A new simultaneous dual-band Fourier domain mode-locked swept laser configuration for dual-band OCT is reported. It was based on a custom-designed dual-channel driver to synchronize two different wavelength bands at 1310 and 1550 nm, respectiv...
متن کاملClinical Applications of Optical Coherence Tomography in Ophthalmology
Assessment of the peripapillary nerve fiber layer and macular thickness can be determined in ophthalmology using optical coherence tomography (OCT). Decreased nerve fiber layer thickness and macular ganglion cell thickness in optic nerve ischemia have been correlated with visual field loss. OCT allows deep optic nerve head evaluation which helps understand pathophysiology of diseases. Furtherm...
متن کاملSimultaneous dual-band ultra-high resolution full-field optical coherence tomography.
Ultrahigh-resolution full-field optical coherence tomography (FF-OCT) is demonstrated in the 800 nm and 1200 nm wavelength regions simultaneously using a Silicon-based (Si) CCD camera and an Indium Gallium Arsenide (InGaAs) camera as area detectors and a halogen lamp as illumination source. The FF-OCT setup is optimized to support the two broad spectral bands in parallel, achieving a detection ...
متن کاملEndoscopic Optical Coherence Tomography for Clinical Gastroenterology.
Optical coherence tomography (OCT) is a real-time optical imaging technique that is similar in principle to ultrasonography, but employs light instead of sound waves and allows depth-resolved images with near-microscopic resolution. Endoscopic OCT allows the evaluation of broad-field and subsurface areas and can be used ancillary to standard endoscopy, narrow band imaging, chromoendoscopy, magn...
متن کاملOptical coherence tomography of band keratopathy.
To cite: Mansour AM, Haddad R. BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2016218216 DESCRIPTION Band keratopathy is a chronic degenerative disease characterised by the gradual deposition of greyish opacity in superficial cornea over months or years in eyes with chronic uveitis or on intensive topical therapies containing phosphates. The mechanism of calcium ...
