Assessment of optic disc morphology is essential in diagnosis and management of visual impairment. The aim of this study was to evaluate associations between optic disc morphometric parameters, i.e., size and shape, and age, gender, and ocular axial length in normal and glaucomatous eyes based on time-domain optical coherence tomography image analysis.It was a case–control study of 998 normal and...
Optical Coherence Tomography is a high resolution imaging technique able to provide in-depth information about living tissue. Among all its applications, it can be argued that surgical guidance is one of the most demanding in terms of system reliability, footprint and cost. In order to enable faster adoption of this technology in that field, we had already developed and demonstrated a new type of...
In recent years optical coherence tomography has been used as a characterization tool of biological tissues with a ten-fold improvement in resolution when compared to ultra-sound. In this paper we present time-domain optical coherence tomography measurements of ex-vivo human samples of stomach tissue with and without neoplasia. Intra-tissue depth of 400 ??m with axial resolution of 8 ??m was achieved.
This paper presents a technique for estimation of amplitude information from an interferometric time-domain optical coherence tomography (OCT) signal. The conventional estimation scheme is based on the in-phase and quadrate (IQ) demodulation concept. A disadvantage of this method is that the IQ components include a ripple whose frequency is the double of the interferometric signal frequency. The improved...
