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, for instance, by NIR/ICG fluorescence imaging – an OPAL1® technology from KARL STORZ.
The use of indocyanine green (ICG) together with light at wavelengths in the near infrared range (NIR) permits visualizing anatomic structures, for instance. KARL STORZ considers fluorescence technology a future standard imaging technique.
IMAGE1 S™ RUBINA – mORe to discover
The new IMAGE1 S™ RUBINA imaging technology from KARL STORZ combines 3D and 4K technology with NIR/ICG fluorescence imaging to support surgeons’ work by supplying high quality information.
NIR/ICG Visualization Modes
The Rubina components offer users various new modes for visualizing the NIR/ICG signal. This includes the overlay of NIR/ICG data onto the standard white light image or alternatively the monochromatic visualization of the infrared signal alone.
In Overlay mode, the regular white light image is combined with the NIR/ICG data to generate an overlay image.
Green or blue – it's up to you
Depending on your preferences and application, the NIR/ICG data can be displayed as a green or blue overlay.
Displays the intensity of the NIR/ICG signal using a color scale in an overlay image.
In this mode, the NIR/ICG signal alone is displayed in white on a black background to achieve the greatest possible differentiation.
Thanks to modular architecture, new 4K, 3D, NIR/ICG, and LED components can be added to the existing IMAGE1 S™ camera platform. The IMAGE1 S™ RUBINA components offer users new options and a series of advantages to support them in their daily routine.

Example Applications of NIR/ICG
Visualization of Perfusion
Perfusion assessment is important in various medical disciplines. With IMAGE1 S™ RUBINA and ICG administration, ischemic areas, perfusion, and vascular structures can be displayed in real time, thereby enabling the surgeon to respond intraoperatively.
- 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
- Display of the cystic artery in cholangiography2
- Visualization of liver segments3 and lung segments4
- Visualization of vessels within and outside of tumor tissue for the improved definition of tumor margins in otorhinolaryngology5
- Multidisciplinary use in laparoscopic, endoscopic, and open surgery

Due to its hepatobiliary excretion, ICG collects in the gallbladder and bile ducts. This allows, for instance, the rapid and easy identification of the biliary anatomy in cholecystectomy.
- Reduced surgical duration with ICG when compared to standard cholangiographies.1 Facilitated differentiation between cystic duct and common bile duct.2
- Visual perceptual illusion is the cause of 97% of bile duct injuries; moreover, 19% of all patients exhibit abnormal anatomic variations of the gallbladder.3
- Display of intraoperative bile leakage with ICG, e.g., following partial hepatectomy.
