The role of optical coherence tomography guidance in scaffold versus stent optimization
The Egyptian Heart Journal, 2020 Background Optical coherence tomography showed a great ability to identify adverse features during percutaneous coronary intervention with drug-eluting stents and resulted in better clinical outcomes.

Optical coherency matrix tomography [PDF]
Scientific Reports, 2015 AbstractThe coherence of an optical beam having multiple degrees of freedom (DoFs) is described by a coherency matrixGspanning these DoFs. This optical coherency matrix has not been measured in its entirety to date—even in the simplest case of two binary DoFs whereGis a 4 × 4 matrix.

Arterial macroaneurysm of the optic disc
American Journal of Ophthalmology Case Reports, 2018 Purpose: We present fundus and spectral domain optical coherence tomography findings of a patient with an arterial macroaneurysm of the optic disc. Observations: An 87-year-old woman presented with blurry vision and was found to have a retinal arterial ...

Panretinal Optical Coherence Tomography
IEEE Transactions on Medical Imaging, 2023 We introduce a new concept of panoramic retinal (panretinal) optical coherence tomography (OCT) imaging system with a 140° field of view (FOV). To achieve this unprecedented FOV, a contact imaging approach was used which enabled faster, more efficient, and quantitative retinal imaging with measurement of axial eye length.

Cross-Polarized Optical Coherence Tomography System with Unpolarized Light
Photonics, 2022 Cross-polarized optical coherence tomography offers improved contrast for samples which can alter the polarization of light when it interacts with the sample. This property has been utilized to screen pathological conditions in several organs.

Optical coherence tomography and scanning laser ophthalmoscopy: Approaches to dual-channel retinal tissue imaging [PDF]
, 2014 We report a Talbot bands-based optical coherence tomography (OCT) system capable of producing longitudinal B-scan OCT images and en-face scanning laser ophthalmoscopy (SLO) images of the human retina in-vivo, with various degrees of ...

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

Der Ophthalmologe : Zeitschrift der Deutschen Ophthalmologischen Gesellschaft, 2004 Optical coherence tomography (OCT) is a high-resolution imaging method for in vivo investigation of the human skin. In cross-sectional images of several millimeters length with a penetration depth of the light signal into deeper parts of the dermis, architectural details of the upper skin layers can be assessed and monitored non-invasively over time ...
