Optical coherence elastography - OCT at work in tissue biomechanics [Invited].

open access: yesBiomedical Optics Express, 2017
Optical coherence elastography (OCE), as the use of OCT to perform elastography has come to be known, began in 1998, around ten years after the rest of the field of elastography - the use of imaging to deduce mechanical properties of tissues.

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).

Decoding glaucoma module premium edition

open access: yesIndian Journal of Ophthalmology, 2022
Background:Traditional methods for neuroretinal rim width measurement in spectral domain optical coherence tomography (SD-OCT) employs the Bruch's membrane opening (BMO) as the anatomical border of the rim, referenced to a BMO horizontal reference plane,

Macular oedema after uncomplicated phacoemulsification

open access: yesAfrican Vision and Eye Health, 2022
Background: Recent development of cataract surgery has led to the improvement of visual outcomes. However, pseudophakic cystoid macular oedema (CME), which is also known as Irvine–Gass syndrome, remains a usual cause of unexpected visual disturbance ...

Paired-angle-rotation scanning optical coherence tomography forward-imaging probe [PDF]

open access: yes, 2006
We report a novel forward-imaging optical coherence tomography (OCT), needle-probe paired-angle-rotation scanning OCT (PARS-OCT) probe. The probe uses two rotating angled gradient-index lenses to scan the output OCT probe beam over a wide angular arc ...

Measurement Floors and Dynamic Ranges of OCT and OCT Angiography in Glaucoma.

open access: yesOphthalmology (Rochester, Minn.), 2019
PURPOSE To determine if OCT angiography (OCTA)-derived vessel density measurements can extend the available dynamic range for detecting glaucoma compared with spectral-domain (SD) OCT-derived thickness measurements.
