Real-time fluorescence imaging with the ENDOCAM Logic 4K platform

System green from Richard Wolf is an excellent visualization of visceral perfusion solution for real-time ICG/NIR fluorescence imaging which meets the highest standards of endoscopic imaging. Indocyanine Green (ICG, available as Verdye in many territories*) is a tricarbocyanine dye, when used with NIR camera systems, will fluoresce and allow visualization of anatomical structures.  

ICG/NIR fluorescence imaging has become one of the most valuable technologies in the field of minimally invasive surgery for applications including intraoperative assessment of visceral perfusion (e.g., enteroanastomosis), visualization of biliary structures in fluorescence cholangiography, or lymph node mapping in oncological procedures (e.g. visualization of the sentinel lymph nodes in case of lymphadenectomy).

* Diagnostic Green is the leading provider of high quality fluorescence products worldwide including ICG. For full prescribing information relating to Verdye, please consult . 


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.


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.
