The new Rubina endoscopy system from KARL STORZ combines vivid 4K resolution with multimode fluorescence-guided imaging. Specialized dual-chip technology lets the surgeon toggle seamlessly between white light and near infrared with remarkable edge-to-edge clarity. The monochromatic mode can be helpful in perfusion assessment. The overlay mode, which superimposes the fluorescent image over the white-light image, accentuates structures that might be hard to discern with the naked eye. The intensity map shows the relative response of the fluorescent dye, providing clues about subsurface features. Rubina is the latest addition to the modular IMAGE1 S system.
