Optical Coherence Tomography and Optical Coherence Tomography with Angiography in Multiple Sclerosis
Healthcare, 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.

Advances in swept-source optical coherence tomography and optical coherence tomography angiography
Advances in Ophthalmology Practice and Research, 2023 Background: The fast development of swept-source optical coherence tomography (SS-OCT) and swept-source optical coherence tomography angiography (SS-OCTA) enables both anterior and posterior imaging of the eye.

Scheme for coherent-state quantum process tomography via normally-ordered moments [PDF]
Phys. Rev. A 95, 032336 (2017), 2017 Using coherent states in optical quantum process tomography is a practically-relevant approach. Here, we develop a framework for complete characterization of quantum-optical processes in terms of normally-ordered moments by using coherent states as probes. We derive the associated superoperator tensors for several optical processes.

Curved-field optical coherence tomography: large-field imaging of human corneal cells and nerves [PDF]
Optica 7, 872-880 (2020), 2020 High-resolution optical imaging methods, such as confocal microscopy and full-field optical coherence tomography, capture flat optical sections of the sample. If the sample is curved, the optical field sections through several sample layers and the view of each layer is reduced.

Doppler Optical Coherence Tomography
Progress in Retinal and Eye Research, 2014 Optical Coherence Tomography (OCT) has revolutionized ophthalmology. Since its introduction in the early 1990s it has continuously improved in terms of speed, resolution and sensitivity. The technique has also seen a variety of extensions aiming to assess functional aspects of the tissue in addition to morphology. One of these approaches is Doppler OCT

Artifacts in optical coherence tomography [PDF]
Saudi Journal of Ophthalmology, 2014 Optical coherence tomography (OCT) is now an integral part of management for numerous retinal diseases for diagnosis, treatment planning and follow up. OCT interpretation must involve the understanding of the associated artifacts. These artifacts can mislead physicians to wrong diagnosis or inappropriate management.
