An overview of optical coherence tomography angiography and the posterior pole

open access: yesTherapeutic Advances in Ophthalmology, 2019
Optical coherence tomography angiography is a relatively new, noninvasive technology that has revolutionized imaging of the retinal and choroidal microvasculature. This technology is based on the detection of movement or changes that represent moving red

Optical tomography dynamics induced by qubit-resonator interaction under intrinsic decoherence

open access: yesScientific Reports, 2022
A superconducting circuit with a qubit and a resonator coupled via a two-photon interaction is considered. When the resonator is initially in a superposition of coherent states, optical tomography and quantum coherence dynamics are examined in the ...

Optical Coherence Tomography in Ophthalmology [PDF]

open access: yesJournal of Ophthalmology, 2012
Optical coherence tomography (OCT) is an optical signal acquisition and processing method that captures micrometer-resolution three-dimensional images from within biological tissues. In recent years, OCT has become an important imaging technology used in diagnosing and following macular pathologies.

Optical Coherence Tomography Angiography in Glaucoma

open access: yesJournal of glaucoma, 2020
Optical coherence tomography angiography (OCTA) is a relatively new, noninvasive, dye-free imaging modality that provides a qualitative and quantitative assessment of the vasculature in the retina and optic nerve head.

Dynamic full-field optical coherence tomography: 3D live-imaging of retinal organoids [PDF]

open access: yesLight: Science & Applications, 2019
Optical coherence tomography offers astounding opportunities to image the complex structure of living tissue but lacks functional information. We present dynamic full-field optical coherence tomography as a technique to noninvasively image living human ...

Cumulative Sum Analysis for the Learning Curve of Optical Coherence Tomography Assisted Diagnosis of Basal Cell Carcinoma

open access: yesActa Dermato-Venereologica, 2020
The amount of training needed to correctly interpret optical coherence tomography scans of the skin is undefined. The aim of this study was to illustrate how cumulative sum charts can be used to determine how many optical coherence tomography scans ...

Optical Coherence Tomography and Optical Coherence Tomography with Angiography in Multiple Sclerosis

open access: yesHealthcare, 2022
Multiple sclerosis (MS) is an inflammatory and neurodegenerative, potentially disabling disease of the central nervous system. OCT (Optical Coherence Tomography) and OCT-A (Optical Coherence Tomography with Angiography) are imaging techniques for the retina and choroid that are used in the diagnosis and monitoring of ophthalmological conditions.

Retinal vascular occlusion in pregnancy: three case reports and a review of the literature

open access: yesJournal of Medical Case Reports, 2022
Background Retinal arterial occlusive events in young patients are rare. However, because of physiological multifactorial adaptations during pregnancy, retinal vascular occlusive disease may occur spontaneously.

Idiopathic Epiretinal Membrane: Microvasculature Analysis with Optical Coherence Tomography and Optical Coherence Tomography Angiography

open access: yesTomography, 2022
Background: The present study examined the relationships among macular microvasculature, retinal structure, and epiretinal membrane (ERM) and explored the utility of optical coherence tomography (OCT) angiography (OCTA) in idiopathic ERM assessment ...

All fiber polarization insensitive detection for spectrometer based optical coherence tomography using optical switch

open access: yes, 2019
Polarization dependent image artifacts are common in optical coherence tomography imaging. Polarization insensitive detection scheme for swept source based optical coherence tomography systems is well established but is yet to be demonstrated for all ...
