Simultaneous ICG/NIR and white light endoscopy with crystal-clear image quality
White light
System green enables standard white light endoscopy with high-resolution image quality at any time. The system can therefore be used without limitations even in white light mode.
greenICG
In the greenICG mode, the conventional white light endoscopic image is simultaneously combined with the ICG/NIR image information in real time, at the touch of a button. This allows the tissue to be differentiated with a high level of detail and contrast, thus allowing the surgeon to easily differentiate anatomy during the surgical procedure.
greenICG pure
The greenICG pure mode enables specific, high-contrast visualization as well as differentiation of tissue structures, e.g., in the case of lymph nodes and the lymphatic channels. The grayscale visualization enables detailed examination of the key structures.
How Fluorescence works
Upon administration, ICG enters the blood stream and immediately binds to the plasma proteins and circulates throughout the entire vascular system. The absorption spectrum of ICG (indocyanine green, Verdye, Diagnostic Green) is located in the near-infrared range (NIR). ICG absorbs the light in the range of 600 nm to 900 nm and emits the fluorescence between 800 nm up to 850 nm. In order to visualise the ICG fluorescence, a ICG / NIR camera system, such as System green is utilised. Thus, it is possible to detect the fluorescence intraoperatively and to visualize fluorescence with System green. The use of NIR light enables the surgeon to see structures more clearly.
