Optical coherence tomography is a near-infrared light based technology that enables to provide cross sectional images with an axial resolution of up to 10-15 mum resulting in a refined analysis of the vessel wall. The main reason why this technology is so infrequently used is both for the ...
INTRODUCTION: One method to acquire dual-energy (DE) computed tomography (CT) data is to perform CT scans at 2 different x-ray tube voltages, typically 80 and 140 kV, either as 2 separate scans, by means of rapid kV switching, or with the use of 2 x-ray sources as in dual-source ...
Elaborate modeling study suggests an important role of capillary transit time heterogeneity (CTTH) reduction in brain oxygenation during functional hyperemia. Here, we use optical coherence tomography angiography (OCTA) capillary velocimetry to probe blo
Optical coherence tomography The anterior chamber of each eye was non-invasively monitored via spectral domain optical coherence tomography (SD-OCT), as previously described [78]. The animals were anesthetized prior to imaging, and 100 µL of water was applied to the cornea surface with a pipet...
Predictive scan aiming for optical coherence tomography imaging during simulated nystagmus Purpose :Patient cooperation to fix gaze and suppress eye motion is a nearly universal strategy for avoiding motion artifacts during ophthalmic imaging. Imaging patients with nystagmus is consequently challenging as the...
Electroretinogram (ERG) recording and optical coherence tomography (OCT) Mice were dark-adapted overnight and all manipulations were performed under low-intensity red light. Anesthesia was achieved by intraperitoneal injection (50 mg/kg ketamine, 0.3 mg/kg medetomidine) and pupils were dilated...
Depth-controlled nanosecond-laser ablation monitored by optical coherence tomography (OCT) was used for automated manufacturing of complex geometries with minimum damage. High shape accuracy with a mean deviation below 50 μm (about 1% of the maximum ablated depth) and a low roughness Sa in the ...
To study changes in vaulting of myopic and toric Implantable Collamer Lenses (ICLs) version 4 during accommodation with Visante optical coherence tomography (OCT), and analyze the relationship between vaulting and anterior subcapsular opacification. Cross-sectional study. Seventy-seven eyes of 77 myopic...
As OCME utilizes phase-sensitive optical coherence tomography (OCT) to measure local strain, it also generates optical contrast and can produce dual-contrast images, called micro-elastograms, by fusing together mechanical and optical contrast. Micro-elastograms improve the ability to detect a broader...
