Data published in late 2016 showed that over 150,000 intracoronary optical coherence tomography procedures are performed every year, and its adoption is rapidly growing at a rate of ~10-20% every year. [19] Assessment of artery lumen morphology is the cornerstone of intravascular imaging criteria to evaluate disease severity and guide intervention.
The split-spectrum amplitude decorrelation angiography (SSADA) algorithm calculates the decorrelation in the reflected light that is detected by the OCT device. The blood vessels are where the most decorrelation occurs allowing them to be visualized, while static tissue has low decorrelation values. [ 39 ]
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 operating room can then be used either with a radiotranslucent non-breakable tabletop that supports 3D imaging, or with a universal breakable tabletop that provides enhanced patient positioning, but restricts 3D imaging. The latter are particularly suited for neurosurgery or orthopedic surgery, and these integrated solutions recently also ...
The FDA authorization for Abbott's (ABT) OCT imaging platform powered by the Ultreon Software is expected to broaden its accessibility to physicians.
Optical coherence tomogram of a fingertip. It is possible to observe the sweat glands, having "corkscrew appearance" Interferometric reflectometry of biological tissue, especially of the human eye using short-coherence-length light (also referred to as partially-coherent, low-coherence, or broadband, broad-spectrum, or white light) was investigated in parallel by multiple groups worldwide ...
Compared to IVUS, intravascular OCT offers an order of magnitude improved resolution for a better visualization of vessel lumen, tissue microstructure and devices (e.g., intracoronary stents). [9] IVUS offers an improved imaging depth for the assessment of lipid or necrotic plaques, while intravascular OCT offers better penetration and enhanced ...
