New aspects of modern endoscopy

Figure 1 Digital chromoendoscopy. Digital chromoendoscopy can be achieved by simply pressing a button on the endoscope. NBI focuses on vessel architecture by narrowing the light spectrum which is emitted to the mucosa. Fujinon Intelligent Color Enhancement System, i-scan and STORZ Professional Image Enhancement System are technologies, which use the reflected light for post-processing light filtering which is used to obtain different effects (like surface, tissue and vessel enhancement).
