In the last decade, clinical benefits of coronary OCT have been systematically investigated. Several studies have linked the use of intravascular imaging such as IVUS and OCT to better stent expansion, a metric strongly correlated to better clinical outcomes in patients suffering from coronary artery disease and myocardial infarction. [12] [13 ...
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 ]
A physician may recommend cardiac imaging to support a diagnosis of a heart condition. Medical specialty professional organizations discourage the use of routine cardiac imaging during pre-operative assessment for patients about to undergo low or mid-risk non-cardiac surgery because the procedure carries risks and is unlikely to result in the change of a patient's management.

The FDA authorization for Abbott's (ABT) OCT imaging platform powered by the Ultreon Software is expected to broaden its accessibility to physicians.
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 .
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 ...
Devices such as ECGs, cardiac MRI machines, and CT scanners can be used to diagnose heart conditions such arrhythmias, heart failure, and coronary artery disease. An ECG provides real-time activity of the heart, allowing for the early diagnosis of abnormalities; a cardiac CT scan allows for a detailed visualization of the coronary artery blockage.
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 ...
