Choroidal Tuberculoma as a Presenting Sign of Tuberculosis

open access: yesNational Board of Examinations Journal of Medical Sciences, 2023
The unusual ocular type of tuberculosis (TB), known as choroidal tuberculoma, poses diagnostic and treatment challenges, particularly when it occurs in the absence of other disease signs.

A deep machine learning model development for the biomarkers of the anatomical and functional anti-VEGF therapy outcome detection on retinal OCT images

open access: yesОфтальмохирургия, 2022
Relevance. Nearly 200 million people worldwide suffer from age-related macular degeneration (AMD), 10% of which is neovascular, the cause of severe vision loss for most patients.

Optical coherence tomography and scanning laser ophthalmoscopy: Approaches to dual-channel retinal tissue imaging [PDF]

open access: yes, 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 ...

Ultra-high resolution Fourier domain optical coherence tomography for resolving thin layers in painted works of art [PDF]

open access: yes, 2013
While OCT has been applied to the non-invasive examination of the stratigraphy of paint layers in recent years, it has been recognized that the resolutions of commercially available OCT cannot compete in depth resolution with conventional microscopic ...

Computed Tomography Biomarkers of Vulnerable Coronary Plaques

open access: yesJournal of Interdisciplinary Medicine, 2016
An unstable plaque has a high risk of thrombosis and at the same time for a fast progression of the stenosis degree. Also, “high-risk plaque” and “thrombosis-prone plaque” are used as synonym terms for characterization of a vulnerable plaque. The imaging

Pump-probe scheme for optical coherence tomography using indocyanine green mixed with albumin or human plasma [PDF]

open access: yes, 2005
Use of indocyanine green (ICG) in a pump-probe scheme for OCT is proposed. The study illustrates that ICG in protein solution shows unusual pump-probe imaging potential, indicating its usefulness as a contrast agent for ...

Inflow mapping method for numerical flow simulations of OCT-based patient-specific vessels using CFD

open access: yesCurrent Directions in Biomedical Engineering, 2017
Alteration of the flow characteristics in coronary vessels is correlated with coronary heart disease (CHD). In particular, wall shear stress (WSS) appears to be a hemody-namic key factor in the genesis of CHD.

Optimal quantum control of Bose Einstein condensates in magnetic microtraps [PDF]

open access: yes, 2007
Transport of Bose-Einstein condensates in magnetic microtraps, controllable by external parameters such as wire currents or radio-frequency fields, is studied within the framework of optimal control theory (OCT).

Sunflower Artifact in OCT

open access: yesJACC: Cardiovascular Imaging, 2011
The sunflower effect is an intravascular optical coherence tomography (IV-OCT) artifact observed when imaging metal coronary stents deployed in patients during cardiac catheterization and appears as a bending of stent struts toward the imaging catheter—analogous to a sunflower bending toward ...
