WebThe history of optical coherence tomography (OCT) reads like a fossil record, with a primordial decades-long process followed by a more recent, explosive evolution in technology. The early ‘protozoal’ period started in the early to mid-1970s at Bell Laboratories (AT&T), where Drs. Duguay and Ippen built the foundation for a concept called ...

WebApr 5, 2024 · 1. Introduction. Optical coherence tomography (OCT) is one of the newest and most important optical non-invasive methods for the investigation and testing of various materials (e.g., tissues) that are at least partly transparent to infrared light. This method is ideal for eye diagnostics, especially of the anterior segment or the retina. WebIntroduction Optical coherence tomography (OCT) is an emerging optical imaging technology that performs high-resolution, cross-sectional tomographic imaging of internal structure in biological systems and materials [1]. OCT is analogous to ultrasound B mode imaging except that it uses light instead of sound. WebNov 13, 2024 · Background Optical coherence tomography angiography (OCTA) can image the retinal vasculature in vivo, without the need for contrast dye. This technology has been commercially available since 2014, however, much of its use has been limited to the research setting. Over time, more clinical practices have adopted OCTA imaging.
