Niris Imaging System
The Niris consists of an imaging console and a detachable fiberoptic Probe
The Niris Imaging System is a valuable tool to aid in the detection and diagnosis of diseases in their earliest stages, precise guidance of biopsy and surgery, and in post-treatment surveillance in a multitude of clinical applications.
A major strength of Niris is the ability to scan epithelial tissue … for example, from the kidneys to the urethra, from the mouth to the anus, from the nose to the lungs, and skin. Sixty percent (60%) of all human cancers originate in epithelial tissue less than 1.4 mm below the surface. Niris provides an optical biopsy by visualizing tissue microstructure to a depth of 2.5 mm, where diagnostically important tissue alterations first occur. Other imaging modalities lack the resolution and depth of penetration to identify structural changes that are associated with the earliest stages of cancer and other disease states.
- Employs harmless, near-infrared light
- Ability to analyze image data in real-time and at the site of care
- Easy to use with minimal training
- True portability
- 8 Frames Per Second (FPS) minimum image acquisition speed for surveillance of large organs or other expanses of epithelial tissue.
- Imaging depth of up to 2.5 mm where the earliest indications of diagnostically important tissue alterations (pre-cancers, early cancers, and inflammatory processes) occur.
- A spatial resolution of approximately 10 – 20 micrometers nearing the resolution of histopathology - 10x the resolution of high speed ultrasound and 100x the resolution of standard ultrasound.
The Niris Imaging System consists of an image management console and docking station, a laptop computer user interface, a flexible optical probe, and accessories.
Image Management Console and Docking Station
The Imaging Console contains optical and electrical components, including a super luminescent diode (SLD). The SLD provides Near InfraRed Light (NIR), which is directed from the console through the Probe’s optical fiber to the patient’s tissue. The optical light is backscattered from the patient’s tissue, collected by the Probe’s fiber, and combined with an internal reference signal, to produce a high spatial resolution image of the superficial tissue microstructure.
From the Image Management Console, one can input patient, physician, and procedure information. For procedure type, anatomical decription and positions, and visual impressions, select from Niris’s extensive database of pull down descriptors or input and store custom comments. Select from three image color palettes.
Niris includes built in protocols for image comparison with automated calculations for intensity and distance. Raw data is also reported. In addition, images can be monitored over time with side-by-side comparisons of a patient’s studies from two time periods or compare a current image with a time-remote image. The Protocol Mode displays up to two normal frames (patient control) and up to 4 abnormal frames. Images are exportable to an ancillary monitor for Picture in Picture viewing.
For billing purposes, Niris’s reporting capability combines text and patient images into a single document.
Niris Imaging Probe
||The Niris Imaging Probe is detachable and available in lengths up to 4 meters. The 2.7 mm front viewing Probe is engineered to work through endoscopes or independently depending on the type of procedure being performed. As an adjunct to an endoscopic exam, the probe can be inserted into the working port of a variety of rigid endoscopes and most flexible endoscopes.
Probes have a limited useful life of approximately 200 patient procedures and can be processed for reuse using commonly available methods, including Sterrad, EtO and STERIS System 1. The Niris probe can also be disinfected using many commercially available alcohol-based disinfectants and Glutaraldehyde. For certain applications, the Probe may be covered by a Niris Probe Sheath to provide physical stability and help prevent cross-contamination.
