The NvisionVLE Imaging System, with Advanced OCT, uses an optical signal acquisition and processing method to create more complete cross-sectional images—letting you evaluate 100% of the tissue in a 6cm scan to better inform your evaluation. 3mm deep. 6cm long. At a resolution of 7 microns. In real time. So you can do more than just look. You can see.

The NvisionVLE Imaging System is indicated for use as an imaging tool in the evaluation of human tissue microstructure, including esophageal tissue microstructure, by providing two-dimensional, cross-sectional, real-time depth visualization. The safety and effectiveness of this device for diagnostic analysis (i.e. differentiating normal versus specific abnormalities) in any tissue microstructure or specific disease has not been evaluated.

A streamlined procedure

The NvisionVLE Imaging System allows clinicians to evaluate the esophageal tissue microstructure in a groundbreaking manner, during a standard endoscopy procedure. The system performs a cross sectional scan through a 6cm length, 3mm deep, enabling visualization of tissue layers including the squamous mucosa, submucosa, and muscularis propria, as well as identification of suspicious areas within the tissue. All so you can provide a more thorough evaluation—potentially leading to improved biopsy targeting for diagnosis by histopathology and more complete information to determine the best treatment for your patients.

An advanced system

NvisionVLE Imaging System Advantages:

  • Captures images up to 3mm beneath the mucosa at a 7 micron resolution in real time—unlike white light endoscopy, which can only image surface detail
  • Offers a full-field view (~10,000mm2), as opposed to a “point” image typically obtained with confocal microscopy (0.25mm2)
  • Advanced Optical Coherence Tomography (OCT) imaging delivers up to 25X higher resolution than endoscopic ultrasound
  • Provides a dramatic increase in imaging speed and improved image resolution, compared to first-generation OCT systems

A faster, better way of seeing

NinePoint Medical's NvisionVLE Imaging System is a groundbreaking convergence of superior optical imaging, innovative engineering techniques, and revolutionary information technology. At the heart of the system, Advanced Optical Coherence Tomography (OCT) technology provides physicians and pathologists with comprehensive, volumetric digital images of a patient’s esophagus. This next-generation technique enables much higher imaging speeds, combined with improved field-of-view and signal-to-noise ratio.

How Advanced OCT works

The (greatly simplified) fundamentals of Advanced OCT are shown in the above diagram. Similar to a traditional laser, the swept-source laser produces light of only one ‘color’ at any instant in time. However, unlike a traditional laser, the swept-source changes the color of its output light very rapidly in time.

The output light is split in two: one beam stays internal to the console, while the second is transmitted through the catheter and focused into the tissue. Some of the light is reflected back from physiological structures within the tissue, and this reflected light is collected by the catheter and returned to the console.

Inside the console, the reflected and internal beams are combined and interfere with each other. After some processing, the interference signal yields an axial line (‘A-line’) that records the intensity of reflections at each depth in the tissue. Combining many consecutive A-lines into an image provides a cross-sectional look at all the reflecting structures in the tissue.

A brief history of OCT

An OCT image is taken every second--over 40 million per year in opthalmology alone

The basic principles of Optical Coherence Tomography (OCT) were initially used within the fields of optical radar and optical telecommunications, among others. The technology expanded in the late 1980s when researchers began exploring applications for biological tissue imaging. Over the next decade, researchers around the world developed sub-categories of the technology, such as swept-source OCT, and began investigating ways to use OCT in different types of tissues and biomedical applications.

Today, commercial OCT systems are used regularly as an imaging standard in ophthalmology, cardiology, dermatology, and general research. NinePoint’s Advanced OCT technology, licensed from the Wellman Center for Photomedicine at Massachusetts General Hospital, initially focuses on esophageal and general imaging of tissue microstructure.

Filling an imaging gap

The ideal imaging system for esophageal surveillance would combine high-resolution scanning, depth, and volume to enable the identification and interrogation of both superficial and buried features.
