The NvisionVLE Imaging Console is designed with clinicians in mind:

• User-friendly controls for physicians and support staff
• Feature-rich user interface for intuitive navigation and high-resolution image management
• Advanced OCT technology enables improved resolution and imaging speed
• Rapid set-up and easy mobility

The NvisionVLE User Interface is designed for flexibility and functionality:

• Visual options for better examination, including image magnification and inverse grayscale
• Easy export of desired snapshots or videos from any portion of the imaging data
• Straightforward correlation between the scanned image and anatomy to aid in targeting

The NvisionVLE Imaging System utilizes a single-use optical probe and lens system that rotates at high speed while retracting within the inner lumen.
Plus:

• Balloon catheter facilitates optical probe positioning and centering
• Available in 14mm, 17mm, and 20mm sizes to accommodate various anatomies
• Atraumatic tip designed to gently flex when in contact with tissue
• Compatible with endoscope channels 2.8mm or larger
• Extremely low noise for polarization diverse balanced detection

Optical Probe Specs:

• 7µm – High-resolution tissue imaging
• >3mm – Near-infrared image depth
• >6cm – Long-length image to capture area of interest
• >10,000mm³ – Volumetric imaging in under 90 seconds
• >105dB – Extremely high sensitivity; able to detect 1.0E-15 watts of light
• >45dB – Wide dynamic range provides high contrast ratio
• >500MBs – Real-time, high-speed data acquisition, reconstruction, and display

NinePoint’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.

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.
