Optical coherence tomography and optical coherence tomography angiography in uveitis: A review [PDF]

Clinical & Experimental Ophthalmology, 2019
Optical coherence tomography (OCT) has dramatically changed the understanding and management of uveitis and other ocular conditions. Currently, OCT angiography (OCTA) combines structural information with the visualization of blood flow within the imaged area.

Phantoms for performance assessment of optical coherence tomography systems [PDF]

, 2012
In this paper, we describe the procedures to make epoxy resin and agarose phantoms designed using Mie scattering calculations. The phantoms are constructed to be used in the estimation of point spread function (PSF) of an optical coherence tomography ...

Optical Coherence Tomography Angiography in Neurodegenerative Disorders [PDF]

Journal of Clinical Medicine, 2020
Retinal microcirculation shares similar features with cerebral small blood vessels. Thus, the retina may be considered an accessible ‘window’ to detect the microvascular damage occurring in the setting of neurodegenerative disorders. Optical coherence tomography angiography (OCT-A) is a non-invasive imaging modality providing depth resolved images of ...

Long wavelength optical coherence tomography for painted objects [PDF]

, 2013
Optical Coherence Tomography has been successfully applied to the imaging of painted objects in recent years. However, a significant limitation is the low penetration depth of OCT in paint because of the high opacity of paint due to either scattering or ...
