Choroidal thickness changes determined by SS OCT following intravitreal bevacizumab

Acta Ophthalmologica, 2013
AbstractPurpose To report choroidal thickness (CT) changes using a SS OCT prototype following intravitreal bevacizumab injections.Methods Seventeen patients were treated by one single intravitreal 1.25 mg injection of bevacizumab (IVB). The macular area was examined using an SS‐OCT prototype system based on swept‐source OCT and was used to image the ...

A novel continuous time ternary encoding based SS-OCT calibration

2016 IEEE Biomedical Circuits and Systems Conference (BioCAS), 2016
In this paper we exhibit a low-complexity asynchronous sampling technique for calibration of swept source optical coherence tomography (SS-OCT) systems. In the proposed scheme, the amplitude content of a Mach-Zehnder interferometer (MZI) signal is equalized by means of a square law envelope detector.

A high speed MEMS scanner for 140-kHz SS-OCT

16th International Conference on Optical MEMS and Nanophotonics, 2011
We present an electrostatic vertical comb-drive MEMS optical scanner with the angle magnifier mechanism developed for a 140-kHz wavelength tunable-laser in the swept-source OCT system of a 2 ms/frame visualization capability.

Angle closure glaucoma detection using fractal dimension index on SS-OCT images

2014 36th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2014
Optical coherence tomography (OCT) is a high resolution, rapid and non-invasive screening tool for angle closure glaucoma. In this paper, we propose a new strategy for automatic and landmark invariant quantification of the anterior chamber angle of the eye using swept source optical coherence tomography (SS-OCT) images.

SS-OCT and FD-OCT System Prototyping Using LabVIEW FPGA

ASME 2011 6th Frontiers in Biomedical Devices Conference and Exhibition, 2011
Optical coherence tomography (OCT) techniques have opened up a number of new medical imaging applications in research and clinical applications. Key application areas include cancer research, vascular applications such as imaging arterial plaque, and ophthalmology applications such as pre and post-operative cataract surgery imaging.
