Perimeter’s S-Series OCT now features ImgClear technology, allowing users to achieve a 28% reduction in scan time, making it more efficient to integrate into the operating room workflow. Additionally, it provides up to a 441% increase in signal-to-noise ratio (SNR), resulting in clearer and more detailed images.

Optical coherence tomography

A single beam of light is directed at the tissue specimen and rapidly moved/translated across the desired scan area. Light that is reflected back from the tissue specimen down from a depth of 2 mm is transformed into an OCT image.

Traditional imaging technologies like X-ray do not have the resolution needed to visualize margins at the cellular level, and all residual disease cannot be detected in the cavity by sight or palpation. Surgeons need advanced technology support in the OR to optimize clinical decision making.

optical coherence tomography是什么

It was a chamber over forty feet long, with dark flock paper and dark curtains, with dark painted wainscoating below the paper, and huge dark mahogany furniture.

OCT provides cross-sectional, microscopic images of tissues down to 2 mm depth, with 10x greater image resolution than standard x-ray and ultrasound, and 100x greater resolution than MRI.

Each light beam captures a single depth profile of a specific area. This single image is called an axial A-scan. As the beam of light moves across the tissue in a line, it generates a long sequence of A-scans that can be compiled into a two-dimensional image known as a B-scan. A series of B-scans can then be stacked to form a three-dimensional image volume.

Research shows that Optical Coherence Tomography (OCT) technology has the potential to increase confidence that the tumor has been excised with sufficient margins or to indicate that taking additional tissue is advisable prior to closing.

Optical Coherence Tomography (OCT) is a non-invasive, optical imaging technique that produces ultra-high-resolution images of subsurface tissue structures.

It was a large room, going far back, and the rich old red flock paper was peeling from the walls in long strips, and blackened with vague patches of rising damp; the ancient clay, the dank reeking earth rising up again, and subduing all the work of men's hands after the conquest of many years.

It was never very light in that room, for the walls were covered with a crimson flock paper and the woodwork was black; while the windows, which looked on the canal, were always shaded till dark.

The luncheon was laid in a low room, with a beam running across the ceiling; the walls, once bright with red flock paper and much gilding, were soiled and dull now, after the manner of a great many of our dining-rooms.

OCT is similar to ultrasound but uses light instead of sound. It is a powerful tool for visualizing suspicious tissue microstructures and features like blood vessels, ducts, and glands. While new to oncology, clinicians have relied on high-resolution OCT imaging for decades to inform their clinical decisions. OCT was developed at MIT in the 1990s and has been widely used in clinical settings ranging from ophthalmology (retina) and interventional cardiology (vessel plaques) to dermatology (skin lesions). Perimeter is the first to use this technology in the operating room for visualizing the margins of excised tissue.
