What is SPY Fluorescence Imaging?
Fluorescence imaging system. SPY Elite Fluorescence Imaging enables surgeons performing open procedures, such as breast and other reconstruction, gastrointestinal and cardiothoracic surgery, to visualize microvascular blood flow and perfusion in tissue intraoperatively.
What is SPY imaging?
Background: SPY Elite imaging uses an injectable fluorescing agent to intraoperatively assess the perfusion and viability of tissue, including skin flaps, during postmastectomy reconstruction for breast cancer patients. The patients were routinely followed up in the clinic postoperatively.
What is Spy angiography?
The SPY System provides a clinically useful assessment of perfusion in a variety of applications, including free and pedicle flaps and mastectomy and other skin flaps [14]. The technique allows for visualization of arterial inflow, venous return, and tissue perfusion during the intraoperative period.
How does spy-Phi work?
SPY-PHI allows clinicians to assess perfusion using a wide range of viewing distances without compromising the strength of signal. SPY-PHI utilizes SPY Fluorescence Imaging Technology to assist surgeons in the visual assessment of tissue perfusion.
What is Spy Phi?
SPY-PHI is a unique and versatile fluorescence imaging system that provides clinicians with a convenient solution for perfusion assessment. Its compact, lightweight design makes it ideal for use in the operating room as well as smaller spaces such as ambulatory surgical centers.
When did Stryker acquire novadaq?
September 1, 2017
Kalamazoo, Michigan – September 1, 2017 – Stryker Corporation (NYSE:SYK) announced today the completion of its previously announced acquisition of NOVADAQ Technologies Inc.
When is a fluorescence microscope used?
Fluorescent microscopy is often used to image specific features of small specimens such as microbes. It is also used to visually enhance 3-D features at small scales. This can be accomplished by attaching fluorescent tags to anti-bodies that in turn attach to targeted features, or by staining in a less specific manner.
How is fluorescence imaging done?
In a fluorescent microscope, a sample is labeled with a fluorophore, and then a bright light (excitation light) is used to illuminate the sample, which gives off fluorescence (emission light). In this manner, samples are highly contrasted to the black background as the fluorophore emits a bright-colored light.
Which microscope uses fluorescent?
A fluorescence microscope is an optical microscope that uses fluorescence and phosphorescence instead of, or in addition to, reflection and absorption to study properties of organic or inorganic substances.
What is a fluorescence microscope used for?
Fluorescence microscopy is highly sensitive, specific, reliable and extensively used by scientists to observe the localization of molecules within cells, and of cells within tissues.
What parts of the microscope are essential for fluorescent imaging?
Typical components of a fluorescence microscope are a light source (xenon arc lamp or mercury-vapor lamp are common; more advanced forms are high-power LEDs and lasers), the excitation filter, the dichroic mirror (or dichroic beamsplitter), and the emission filter (see figure below).
