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 ]
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 ...

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 ...
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.

Advisers to the U.S. Food and Drug Administration on Tuesday backed an approval for Abbott Laboratories' heart valve repair device that is designed for patients who are at risk of complications or ...
Used primarily in ultrasound imaging, capturing the image produced by a medical imaging device is required for archiving and telemedicine applications. In most scenarios, a frame grabber is used in order to capture the video signal from the medical device and relay it to a computer for further processing and operations.
