In endoscopic surgery, detecting structures earlier and differentiating them better is a necessity. The imaging technology has to replace the missing view of the open site. Alongside an optimal image, it is helpful to receive additional information that increases the precision of the surgical technique. This information is supplied by NIR/ICG fluorescence imaging – an OPAL1® technology from KARL STORZ.
The use of indocyanine green (ICG), a non-radioactive, inexpensive fluorescent dye, together with light at wavelengths in the near infrared range (NIR) permits visualizing anatomic structures, perfusion and perfusion defects as well as the lymphatic system. The high penetration depth of NIR light allows visualizing the distribution of ICG up to a depth of 10 mm below the tissue surface.
In response to the current professional interest in the topic – in 2015 alone, more than 600 publications were published on ICG (NCBI database) – the OPAL1® technology for NIR/ICG will continue to steadily adapt to market demands. Due to its versatile cross-discipline applications, KARL STORZ considers this fluorescence technology as a future standard imaging technique that will be found in every OR.
IMAGE1 S™ Rubina – mORe to discover
The new IMAGE1 S™ RUBINA imaging technology from KARL STORZ combines 3D and 4K technology as well as fluorescence imaging with NIR/ICG to supports surgeons’ work by supplying the highest-quality information.
Green or Blue – You Decide!
The OPAL1® technology for NIR/ICG now comes with a new color option. The preferred color can be selected on IMAGE1 S™ before or during the procedure.
NIR/ICG imaging in green offers high-intensity fluorescence with clear differentiation from the surrounding tissue. It additionally achieves slight optical brightening of the background.*
In comparison, NIR/ICG imaging in blue delivers fluorescence visualization that appears more balanced to the eyes, particularly for the well-perfused liver. In the process, potential overexposure of the signal in highly fluorescent areas is avoided.
*The SPECTRA A visualization mode is not available with green.
*The approval status of the fluorescent dye may vary. Before using it, please determine the status applicable at your hospital or in your country.
- Image quality
Most surgery is performed under white light. We deliver razor-sharp FULL HD images for all white light applications as well as our S-Technologies.
Our technology is Xenon-based. This eliminates the need for additional laser safety precautions such as, for example, laser safety goggles or laser protection officers in the operating room.
- Modularity with our all-in-one solution
Based on our IMAGE1 S™ camera platform, we provide a modular system that offers forward and backward compatibility and, consequently, sustainability. In accordance with individual needs, the system can be expanded at any time and various modules such as, for example, components for both open and laparoscopic procedures can be used simultaneously in one camera system.
- German quality
As a system provider, the company combines years of experience in endoscopy with software solutions that ultimately provide brilliant visualization. Furthermore, we have been working very intensively for many years on various fluorescence procedures, e.g., NIR/ICG fluorescence imaging.
- Virtual support thanks to SCENARA® .store
SCENARA® .store provides better orientation for user documentation. With its preview and navigation options, SCENARA® .store permits easy retrieval and playback of, for example, fluorescence sequences for consultations with patients or team meetings and thus eliminates tedious searching.
In addition, the software offers many other benefits such as, for example, the possibility to edit, cut, compare and export video and image material as well as seamless storage in existing information and archiving systems.
KARL STORZ is synonymous with quality products and offers a first-class service. We are always there for you when you need us!
As a manufacturer of endoscopes with countless years of experience, we have a global presence and are at your disposal at any time.
Visualization of Perfusion
Perfusion assessment is important in various medical disciplines. With NIR/ICG technology and the administration of ICG, ischemic areas can be displayed in real time more easily and efficiently, or perfusion can be examined, for instance in anastomoses. This enables the surgeon to take intraoperative action.
- Rapid perfusion assessment of a planned resection zone as well as of the subsequent anastomosis, e.g., in colon1 or esophageal resection and gastric bypass2.
- Perfusion assessment of flap plasty in open surgery
- Visualization of liver segments3
- Multidisciplinary use in laparoscopic, endoscopic, and open surgery

Visualization of the Biliary Tree Anatomy
Due to its hepatobiliary excretion, ICG collects in the gallbladder and bile ducts. This allows the rapid and reliable identification of the biliary anatomy, for instance in cholecystectomy.
- Reduced surgical duration with ICG when compared to standard cholangiographies.1 Facilitated differentiation between cystic duct and common bile duct.2
- Display of intraoperative bile leakage with ICG, e.g., following partial hepatectomy
