Pupil Tracking for Real-Time Motion Corrected Anterior Segment Optical Coherence Tomography
Volumetric acquisition with anterior segment optical coherence tomography (ASOCT) is necessary to obtain accurate representations of the tissue structure and to account for asymmetries of the anterior eye anatomy. Additionally, recent interest in imaging of anterior segment vasculature and aqueous humor flow resulted in application of OCT angiography techniques to generate en face and 3D micro-...
متن کاملAnterior Segment Time Domain Optical Coherence Tomography
To compare anterior segment parameters using quantitative imaging by anterior segment time domain optical coherence tomography (AS-OCT) and high frequency ultrasound biomicroscopy (HF-UBM). SETTING: Department of Ophthalmology at Bari University. METHODS: Seventy-two eyes of 72 subjects had anterior segment evaluation by AS-OCT (Stratus ver 6Zeiss) and HF-UBM (OTI-Scan HF35-50). Central corneal...
متن کامل[Anterior segment optical coherence tomography in glaucoma].
In recent years, the rapid development of diagnostic optic devices has generated optical coherence tomography (OCT) as a new, non-invasive diagnostic method. With technical progress of the infrared spectrum at 1,310 nm, OCT of the anterior segment also became feasible. With anterior segment OCT different examinations which so far were ruled out by ultrasound in contact manner could be executed ...
متن کاملImaging the ocular anterior segment with real-time, full-range Fourier-domain optical coherence tomography.
We have demonstrated a novel Fourier-domain optical coherence tomography system and signal-processing algorithm for full-range, real-time, artifact-free quantitative imaging of the anterior chamber. Cross-sectional full-range images comprising 1024 x 800 pixels (axial x lateral) were acquired and displayed at 6.7 images/s. Volumetric data comprising 1024 x 400 x 60 pixels (axial x lateral x ele...
متن کاملReal-time optical coherence tomography of the anterior segment at 1310 nm.
BACKGROUND Recent advances in high-speed scanning technology have enabled a new generation of optical coherence tomographic (OCT) systems to perform imaging at video rate. Here, a handheld OCT probe capable of imaging the anterior segment of the eye at high frame rates is demonstrated for the first time. OBJECTIVE To demonstrate real-time OCT imaging of anterior segment structures. DESIGN S...
