WebFeb 10, 2024 · Optical coherence tomography (OCT) is a high resolution cross-sectional imaging modality initially developed for retinal imaging. Anterior segment OCT (ASOCT) imaging was first described in 1994 by Izatt et al [1] using the same wavelength of light as retinal OCT, namely 830nm. This wavelength is suboptimal for imaging the angle due to … WebOverviewMagnetic resonance imaging (MRI) systems provide highly detailed images of tissue in the body.
