The first demonstrations of in vivo OCT imaging quickly followed. [3] [4] [5] The first US patents on OCT by the MIT/Harvard group described a time-domain OCT (TD-OCT) system. [6] [7] These patents were licensed by Zeiss and formed the basis of the first generations of OCT products until 2006.
The first intravascular in vivo use in a preclinical model was reported in 1994 [6] and first in human, clinical imaging in 2003. [7] The first OCT imaging catheter and system was commercialized by LightLab Imaging, Inc., a company based in Massachusetts formed following a technology transfer in 1997 from Fujimoto's lab (MIT).

Optical coherence tomography is an imaging modality that uses low-coherence interferometry to obtain high resolution, depth-resolved volumetric images. OCT can be used to capture functional images of blood flow, a technique known as optical coherence tomography angiography (OCT-A). SV-OCT is one method for OCT-A that uses the variance of ...
Dual-axis optical coherence tomography (DA-OCT) is an imaging modality that is based on the principles of optical coherence tomography (OCT). These techniques are largely used for medical imaging. OCT is non-invasive and non-contact. It allows for real-time, in situ imaging and provides high image resolution.
Medical optical imaging is the use of light as an investigational imaging technique for medical applications, pioneered by American Physical Chemist Britton Chance. Examples include optical microscopy , spectroscopy , endoscopy , scanning laser ophthalmoscopy , laser Doppler imaging , optical coherence tomography , and transdermal optical imaging .
The FDA authorization for Abbott's (ABT) OCT imaging platform powered by the Ultreon Software is expected to broaden its accessibility to physicians.
Doppler Optical Coherence Tomography is an extension of OCT, where it combines the Doppler effect principle to achieve high resolution tomographic images in biological tissues. And because of its high resolution and velocity sensitivity, there are many applications in the medical field. The basic phenomenon of Doppler OCT can be explained below.
The Gibralt OCT system includes polyaxial screws and cannulated screws in multiple diameters and lengths, hooks, rods, rod-to-rod connectors, offset connectors and cross connectors to provide ...
