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